Complete question:
A gene has a base sequence of GTC. Due to a mutation, the base sequence changes to GTG. Answer the following questions:
a) What are the bases of mRNA coded for by this section of DNA, before the mutation? (1 point)
b) What are the bases of mRNA coded for by this section of DNA, after the mutation? (1 point)
c) What amino acid is coded for by this sequence before the mutation? (1 point)
d) What amino acid is coded for by this sequence after the mutation? (1 point)
e) Is this is a silent mutation or a missense mutation? Explain. (1 point)
Answer:
a) mRNA before mutation ⇒ CAG
b) mRNA after mutation ⇒ CAC
c) amino acid before mutation ⇒ Glu, Glutamine
d) amino acid after mutation ⇒ His, Histidine
e) missense mutation
Explanation:
Theoretical frame
Transcription:Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
The template strand is the mRNA complement.
The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
Translation:Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells
• The end codons are UAA, UAG, UGA.
When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.
----------------------------------------------------------------------------------------------------------
In the exposed example,
Before mutation
Original DNI base sequence ⇒ GTC ⇒ Guanine, Timine, CytokineTranscripted mRNA sequence ⇒ CAG ⇒ Cytokine, Adenine, GuanineAmino acid ⇒ Gln ⇒ GlutamineAfter mutation
Mutated DNI base sequence ⇒ GTG ⇒ Guanine, Timine, GuanineTranscripted mRNA sequence ⇒ CAC ⇒ Cytokine, Adenine, CytokineAmino acid ⇒ His ⇒ HistidineThis is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.
Before mutation, the mRNA codon is CAG and codes for Glutamine.After mutation, the mRNA codon is CAC and codes for Histidine.Imagine a molecule of free glucose in the blood after a large meal. Which of the following statement is/are true?
a. Be converted to fructose-2,6-bisphosphate in a liver cell
b. Become a glycerol backbone in a triglyceride in an adipose cell
c. Become part of a fatty acid chain in a triglyceride in an adipose cell
d. Be polymerized into glycogen in a skeletal muscle cell
e. Be phosphorylated and bind allosterically to glycogen synthase
Answer:
e. Be phosphorylated and bind allosterically to glycogen synthase
Explanation:
The initial step in the pathways that utilize glucose is its phosphorylation in C6. Glucose-6-phosphosate
The statement that is true is phosphorylated and binds allosterically to glycogen synthase. The correct option is e.
What is phosphorylation?Phosphorylation is a biological process in which a phosphate group is added to an organic molecule. Phosphorylation processes include the following:
1) phosphate added to glucose to generate glucose monophosphate
2) Phosphate addition to adenosine diphosphate (ADP) to generate adenosine triphosphate (ATP).
Phosphorylation regulates several biological functions, including cell cycle, proliferation, death, and signal transduction pathways.
ADP-phosphate group of a reactive intermediate with the transfer of a chemical reaction in which ATP is created in substrate level phosphorylation.
Therefore, the correct option is e. Be phosphorylated and bind allosterically to glycogen synthase.

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?
Answer:
Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.

Which best describes chromosomal dilatation
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

Cell processes that increase the surface area of a cell are called:
Answer:
Answer below
Explanation:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly).Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration.These foldings too increase the surface area.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Non-motile cilia are structures in a cell membrane that also increase surface area. Non-motile cilia are like oars that push through the cell membrane. They are thinner and longer than microvilli. Non-motile cilia are also called primary cilia.

What is likely to happen to the ecosystem pictured below after a period of time? Erupting volcano and magma. A. The ecosystem will undergo only primary succession. B. The ecosystem will undergo only secondary succession. C. The ecosystem will undergo primary succession followed by secondary succession. D. The ecosystem will never recover.
An ecosystem is defined as the geographical region, in which plants, organisms, and animals with abiotic factors like weather, water, and landscape. The ecosystem that changes over time is known as ecological succession.
The correct answer is:
Option C. The ecosystem will undergo primary succession followed by secondary succession.
Ecological succession can be defined as:
1. Ecological succession refers to the change in the structure of the species in an ecological community over time.
2. The primary ecological succession begins in the lifeless region, such as the regions with no soil or incapable of sustaining life. In this, newly formed rock is colonized by living organisms for the first time.
3. The primary succession will be followed by the secondary succession, in which the organisms tend to re-habitat the area that has been destructed due to natural or human-made events.
Thus, in the given picture, the primary ecological succession is followed by the secondary ecological succession.
