Answer: B.
Explanation: As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
The statement that correctly describes the difference between the semi-conservative model of DNA replication and the conservative model of DNA replication is as follows:
The semi-conservative model states single-stranded DNA strands are used as template strands to create newly synthesized DNA strands and the conservative model states only one side is used as a template.Thus, the correct option is B.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact. While in the conservative model of DNA replication, the entire original form of the DNA double helix function as a template and synthesize a new double helix.
Therefore, the correct option for this question is B.

b. The HDR fragment must enter the of the yeast cell to be used for homology directed repair.
c. The Cas9 gene is transcribed from the ____________as template, the transcript is transported from the _______to the ____________of the cell, and then the protein is translated.
d. After translation of Cas9, what happens? Explain in ONE sentence.
Answer:
a. The guide RNA (gRNA) is transcribed from the PML 104-9RNA1 plasmid vector
b. It is correct. The homology-directed repair (HDR) fragment of interest enters into the cell and is then inserted at the site of the original double-strand breaks (DSBs) via the HR DSB repair pathway.
c. plasmid, nucleus, cytoplasm
d. Once Cas9 is transcribed, this nuclease forms a complex with the gRNA and cuts the target DNA, thereby inducing a DNA double-strand break (DSB) which is repaired either by non-homologous end joining (NHEJ) or homology-directed repair (HDR)
Explanation:
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas (i.e., CRISPR-associated protein 9) is a natural prokaryotic defense mechanism against foreign viral invaders. In genome engineering, this system has been adapted to create a versatile RNA-programmable genome editing technique. Cas9 is an RNA-guided endonuclease capable of recognizing and cleaving a target DNA complementary to the guide RNA (gRNA). The gRNA is a specific RNA sequence formed by two small RNAs (crRNA and tracrRNA), which binds to the Cas nuclease enzyme and guides the gRNA-Cas9 complex to the target DNA sequence.

Answer:
The livestock waste fertilizes the grasses
Explanation:
A negative ecological impact is one that is detrimental to the ecosystem or that results in a disadvantage to organisms in the ecosystem.
When livestock graze on rangelands, it would result in both positive and negative impacts to the rangeland.
Some of the negative impacts includes those listed in the options. For example:
1. The weight of the grazing cattle as they move around to graze will compact the soil. This compaction of the soil will reduce aeration of the soil as well as the fertility of the soil.
2. The livestock may eat too much grass which is known as overgrazing. Overgrazing will not give the plants enough time to regrow before they are eaten. this will eventually result in too few grasses growing in the rangeland.
3. Increased wind and water erosion due to overgrazing. as the livestock graze, they remove grasses which help to reduce wind and water erosion on the soil. This results in loss of soil fertility.
However, an advantage of grazing on the rangeland as the livestock graze is that the wastes of the livestock serves as a source of manure for the grasses which fertilizes the soil and makes the grasses grow.

When DNA replicates, each strand of the original DNA molecule is used as a template for the synthesis of a second, complementary strand. Compare and contrast the replication of the two new strands, listing and explaining at least one similarity and one difference in the methods of synthesis.
Answer:
See the answer below
Explanation:
A typical double-stranded DNA consists of a leading and a lagging strand with 5' to 3' direction and 3' to 5' direction respectively. During replication, a RNA primer binds to each strand at the replication origin and DNA polymerase enzyme adds complementary nucleotides to the primer to elongate the new strand until the end of each strand is reached.
The replication process of the two strands are similar such that:
Both require RNA primer bindingBoth require DNA polymerase to add nucleotides in 5' to 3' directionThe replication of the two strands are different in a certain way:
The enzyme responsible for adding nucleotide bases to the growing DNA strand during replication can only add in 5' to 3' direction. Consequently, the leading strand is synthesized in a continuous manner while the lagging strand is synthesized discontinuously in short nucleotide sequences known as the Okazaki fragments. The fragments are later joined together by an enzyme known as DNA ligase.This means that the RNA primer only binds at a single location on the leading strand while multiple primers bind at multiple locations on the lagging strand.

Waves erode the bedrock along the coast largely by abrasion. The suspended sediment particles in waves, especially pebbles and larger rock debris, have much the same effect on a surface as sandpaper does. Waves have considerable force and so may break up bedrock simply by impact.
he G-protein-linked receptor is located ___________________. When GDP is attached to the G protein the messenger is considered _______. GTP replaces GDP and now the messenger is considered _______. The G protein carrying the GTP leaves the receptor and _______ and enzyme which causes a cellular response. All of this is brought on by a _______ ________ attaching to the G-protein-linked receptor and will shut down quickly when the ___________ ____________ is no longer there.
Answer:
located... on the plasma membrane
is considered... inactive
the messenger is considered... to be active
All of this is brought on by a.... signal molecule
will shut down quickly when the.... signal molecule
Explanation:
The G protein-coupled receptors (GPCRs) are transmembrane proteins found on the plasma membrane. GPCRs are considered to be the most diverse group of transmembrane receptors in eukaryotic cells. These proteins (GPCRs) bind to signaling molecules to trigger signaling pathways through Guanine nucleotide-binding proteins (G-proteins). G proteins are signaling proteins (for example, Ras protein) that bind both GTP and GDP. After the signaling molecule binds to GPCR, GTP is hydrolyzed by the G-protein in a process that triggers specific signaling pathways (for example, activation of the production of second messengers).

Which discovery supported the endosymbiotic theory?
The discovery of independent DNA (from the host) in mitochondria and chloroplasts supports the endosymbiotic theory.
The endosymbiotic theory is the theory that mitochondria and chloroplasts, two important organelles found in eukaryotic cells, originated from bacteria that were engulfed by larger cells.
What is this theory?The presence of DNA in mitochondria and chloroplasts. Mitochondria and chloroplasts have their own DNA, which is separate from the DNA in the nucleus of the cell. This suggests that they were once independent organisms.
The similarity of mitochondrial and chloroplast DNA to bacterial DNA. The DNA in mitochondria and chloroplasts is similar to the DNA of bacteria. This suggests that they share a common ancestor.
The presence of ribosomes in mitochondria and chloroplasts. Mitochondria and chloroplasts have ribosomes, which are structures that are used to make proteins. Ribosomes are also found in bacteria.
