6-48 In somatic cells, if a base is mismatched in one new daughter strand during DNA replication, and is not repaired, what frac

tion of the DNA duplexes will have a permanent change in the DNA sequence after the second round of DNA replication

Vinvika [58]3 years ago
5 0

Answer:

1/4

Explanation:

DNA replication is semi-conservative, which means that during this process one DNA strand will be from the original DNA template, whereas the other DNA strand will be newly synthesized. In the first round of DNA replication, daughter cells receive a DNA molecule containing one original DNA strand and one newly-synthesized DNA strand (in this case, one of these daughter cells will contain a mismatch). If the mismatch is not repaired, then in the second round of replication the DNA molecule containing the mismatch would separate during replication, and the DNA strand containing the erroneous nucleotide will serve as a template for the synthesis of a new DNA molecule, thereby producing a permanent mutation.

A plant contains the alleles Gg for green pod
Viefleur [7K]

Given:

Allele for green pod colour = Gg (Heterozygous)

Allele for Yellow pod colour = gg (Homozygous)

Explanation:

Parents: Gg x   gg

When this two parent are crossed, it leads to the following F1 generation (off springs):

<em>• Gg (green colour pod) </em>

<em>• Gg (Green colour pod) </em>

<em>• gg (Yellow colour pod) </em>

<em>• gg (Yellow colour pod) </em>

Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.

Do all living tissues contain catalase? Claim, evidence, and reasoning
allsm [11]

Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

<h3>Do all living tissues contain catalase?</h3>

Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.

Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.

So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
