Why is it important for a cell to perform checks after DNA replication?

Ans. (D) If errors are not removed from areas with a gene, then the resulting proteins could be affected.

DNA replication involves synthesis of replicas (exact copies) of DNA molecule, at the time of cell division.

DNA contains information for the protein synthesis in the form of triplets of nucleotides, called as codons. It transfers this information to the mRNA and mRNA used this information to code polypeptide chain or protein.

If an error, occurred during DNA replication gets not repaired, it would alter the sequence of DNA. The mutated DNA would transcribe altered mRNA that would code for a mutated or altered protein.

Thus, the correct answer is option (D).

Which of the following is NOT a part of an ATP molecule? Select one: a. adenine b. ribose c. chlorophyll d. phosphate
Gnesinka [82]

Answer:

C (Chlorophyll)

Explanation:

Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.

ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.

Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.

The Sanger method of DNA sequencing uses a mixture of dNTPs and ddNTPs, which are missing oxygen atoms at both the 2' and 3' car
sdas [7]

The role of the ddNTPs is to stop replication because the next nucleotide in the growing strand cannot bind to them. It is for that reason that ddNTPs are fundamental in Sanger sequencing.

<h3>Sanger sequencing</h3>

Sanger sequencing is a technique used to sequence and thus determine the nucleotide order of a DNA chain.

This methodology (Sanger sequencing) was designed by Frederick Sanger in 1977.

In Sanger sequencing, the ddNTPs are used to stop the synthesis of a DNA strand due to the lack of a free hydroxyl group (OH) which is required for the replication of DNA.

Homologous recombination can be used in the lab to replace a gene of interest with a selection marker. To confirm that the selec
Luden [163]

Answer:

b. A second marker in the knock-out cassette, that if inserted into the genome results in cell death when plated on selective media.

Explanation:

General recombination, also known as homologous recombination, refers to the naturally occurring process of exchange of genetic material between pairs of homologous DNA sequences. This process (homologous recombination) can be exploited by genetic engineering to insert DNA segments of interest at target genes. Moreover, a cassette is a mobile DNA segment containing almost a gene and a recombination site, which is integrated into the <em>locus</em>/<em>loci</em> of interest by homologous recombination. A cassette may contain a DNA segment called 'negative marker' which prevents growth under particular conditions, while a positive marker permits growth under certain conditions. In consequence, a second marker consisting of a drug cassette may be used as a negative marker in order to evidence its insertion by inducing cell death when they are plated in selective conditions.

vladimir2022 [97]

Answer:

C) 3

Explanation:

So the one that has a group of three would be the Passive Transport the first one's effect would be Diffusion and the second and third are both together which will be Facilitated diffusion Hope this helps!

The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.
