The central dogma of molecular biology states that DNA is _______ into mRNA, which is then translated into polypeptides.
Eukaryotic ribosomes exist freely floating in the _______ and membrane-bound.
In peptide synthesis, after an amino acid has been added to the polypeptide chain, the empty _______ exits the ribosome.
Answer:
transcribed
cytoplasm
tRNA
Ribosomes are located in the cytoplasm, the fluid material that comprises the cell. In prokaryotes, ribosomes freely float in the cytoplasm. In eukaryotes, ribosomes can be both freely floating and membrane-bound. The ribosome's role in gene expression is to synthesize proteins based on the instructions provided by mRNA. The mRNA strand is made from the cell's DNA and tells the ribosome how to construct the cell's necessary proteins.
The ribosome is essential for protein synthesis, so it is part of translation and not transcription. The ribosome reads instructions from mRNA and "translates" them into proteins.
Prokaryotes and eukaryotes have some major structural differences, so the details of protein synthesis differ between these two types of organisms as well. Prokaryotic organisms such as bacteria do not have a cell nucleus, so the cell's DNA floats freely in the cell. In eukaryotic organisms such as humans, the cell's DNA is located in the nucleus, while the ribosome is located in the cytoplasm.
Eukaryotic ribosomes are also larger and more complex than prokaryotic ribosomes.
Transfer RNA, or tRNA, provides a physical link between the codons of the mRNA and the amino acids to be added to the polypeptide chain. Specific tRNA molecules are bound to specific amino acids, and tRNA that is complementary to the mRNA codon enters the ribosome and transfers its amino acid to the growing polypeptide chain.
Ribosomal RNA, or rRNA, is an important component of the ribosome. Both eukaryotic and prokaryotic ribosomes contain rRNA. rRNA and proteins together carry out the functions of the ribosome.
If there are no ribosomes present in the cell, proteins cannot be made. Without protein synthesis, cells cannot accomplish their necessary functions, and the organism will die.
Explanation:
Blood is a critical body fluid. What role does blood play in the body? How is it usually cleaned, and how is it cleaned during dialysis?
Answer: Dialysis cleans your blood by passing it through a filter. If you do peritoneal dialysis (PD), the filter is the lining of your abdomen (your peritoneum). If you do hemodialysis, the filter is made of plastic. Your blood is on one side of the filter.
Explanation:Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

The water comes from cellular respiration when a plant is left in a closed clear container and this process is called transpiration. Hence, option B is correct.
What is transpiration?The process of transpiration occurs when plant roots take in water and then release it as vapor through the leaves. As one of the primary sources of water entering the atmosphere, transpiration plays a significant role in the water cycle.
In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling. Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration.

The epicenter of an earthquake is the area where the least amount of damage takes place.
Answer:
Yes it can be.
Explanation:
Surface damage. The epicenter is directly above the earthquake's hypocenter (also called the focus). In most earthquakes, the epicenter is the point where the greatest damage takes place, but the length of the subsurface fault rupture may indeed be a long one, and damage can be spread on the surface across the entire rupture zone.

Which of the following best summarizes the process of DNA replication?
DNA replication is the process through which cells make copies of the genome's DNA.
What is DNA Replication?A cell must first copy (or duplicate) its entire genome before it can divide, ensuring that each daughter cell has a complete genome upon division.
One of DNA's most astounding tricks is likely DNA replication. If you stop to think about it, every cell has all the DNA required to create every other cell.
Therefore, DNA is a molecule that can be copied to create almost exact duplicates of itself. Considering that there are over three billion base pairs in DNA that need to be copied, this is even more astounding. DNA polymerases, which are molecules dedicated solely to copying DNA, are also used in replication.
Therefore, DNA replication is the process through which cells make copies of the genome's DNA.

What are the types of pollination? How is one advantages over the other method?
Explanation:
In self-pollinating plants, there is less dependence on the external factors to cause pollination. These plants depend on wind or other smaller insects that visit the flower regularly. In self- pollinating flowers, the anthers, and stigma are of similar lengths to facilitate the transfer of pollen.
Answer:
The two types of Pollination are Self Pollination and Cross Pollination.
Explanation.
During the process of fertilizations in green plants ,mature gametes (pollen grains) are transferred from the male reproductive parts(flowers) of plants(anther) to the receptive female reproductive parts of the same plants or another plants of the same species(stigma) for fertilizations to take place .This process is called Pollination.
If the transfer takes place between the anther and stigma of the same plants, this is Self pollination. However if between the anther and stigma of another plants, but of the same species it is called cross pollination.
Therefore, the two types;
• Self-Pollination
• Cross pollination.
Self-Pollination.
This is one of the process of reproduction in hermaphrodite or monoecious Plants. Plants with male and female reproductive parts in their flowers.
• The reproductive parts(anther and filament) are naturally created close to one another in most cases.
• They are also of propionate length to facilitate the the reacceptance of pollen grains from anther on the stigma.
• The stamen and carpel usually mature at the same time to aid pollination.
.Its advantages are-
• No diversity of genes since there is no cross over at meiosis, therefore the genome is pure for progeny of similar traits to the parents.
•
• Its allow the manifestation of the recessive allele, and therefore stability of the same type of parent plant from generation to generation.
• Does not depend on external factors or agents. therefore, pollen grains are not wasted. Pollination is usually 100% success rate.
• Disadvantages.
• Lack of variation leads to plants with loss of vigor. This affect the quality of offspring produced.
• The progenies has low resistance to diseases leading to poor yield. This may lead to loss of the plant lineage with time because plants with high vigor may evolve with time, based on Darwin Theory.
• Cross pollination.
This occurs in Dioecious plants. That is plants with district male and female reproductive flowering parts.
It depends on the external factors or agents of wind, water, animals (including human) insects to take place. These factors transfer(i.e Cross) the mature pollen from the anther of one flower to the stigma of the another flower of another plants but of the same species. Based on the agent of pollination, cross pollination can be placed into different groups.
Advantages.
Since there is blend of traits among different plants of the same species, there is diversity of genes through variation. This ensures;
Progeny with characteristics different from each of the parents Hybrid). The beneficial effects of these are;
High vigor.
High resistant to diseases.
High yield.
Evolution of new species over time.
However, wastage of pollen in transition and loss of good traits through the agents are few disadvantages. Although plants make up for this with large amount of pollen produced.
Because cross pollination allow genetic diversity through blending of genes from different plants of the same species, it ensure survival of the plants with better vigor more than self pollination because the progeny becomes weak and later edged out by the more dominant progeny from the cross palliation.
This is the survival of the fittest by natural selection.

Complete this exercise and answer the questions that follow. You will use the DNA strand (A G C A A T C C G T C T T G G) from Exercise 8 on p. 48 of your lab manual to make the protein for which it codes. Follow steps 1-6 on pp. 50-51 of your lab manual for this exercise. What is the amino acid sequence for the mRNA strand that you drew in step 6
Answer:
Amino acid sequence:
Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The)
Explanation:
This question is related to gene expression, which involves the transcription of DNA sequence into mRNA, and the subsequent translation of mRNA into amino acid sequence (protein).
- The transcription of a DNA sequence into mRNA is based on complementary base pairing rule i.e. A-T, G-C. Based on this pairing rule, the DNA sequence (AGC AAT CCG TCT TGG) will be transcribed into UCG UUA GGC AGA ACC.
- Using the genetic code which contains codons that encode amino acids, the mRNA sequence (UCG UUA GGC AGA ACC) will be translated into the amino acid sequence as follows: Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The).
A farmer wants to interbreed only white peacocks, since he can sell them for more money than the regular peacocks! What is the best question to ask to determine the effects of
interbreeding the white peacocks?
Answer:
Are there risks of mutations by interbreeding?
Explanation:
Selective breeding can be defined as the production of offspring by the mating of organisms in a given group to obtain desired phenotypic characteristics. White peacocks are closely related individuals that have a genetic mutation (leucism) that produces the lack of pigmentation in their plumage. It is well known that interbreeding between close relatives (inbreeding) increases the risk of recessive genetic disorders because organisms that are genetically closely related have more chances to carry a copy of the same recessive genes, which may or not contain recessive deleterious mutations. In consequence, in this case, it seems reasonable to ask if there risks of negative impacts caused by recessive deleterious mutations.
