The phosphodiester bonds of the polynucleotide backbone in DNA would be broken.

The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds).

Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.

As there are no answer choices, I'm going to answer this just based off my knowledge

Analogous structures suggest convergent evolution because they have both evolved from a set of species but for different reasons and from different causes.

What would be the consequence to an organism if they are missing the following DNA repair mechanisms:
sp2606 [1]

Answer:

a. DNA polymerase proofreading:   consequence of its absence is the DNA mutation

b.  Mismatch repair enzymes : consequence of its absence impedes homologous recombination resulting in the final mutation

c. Nucleotide excision repair enzymes : the absence of nucleotide cleavage repair enzymes would impede the functioning of damaged DNA repair mechanisms

Explanation:

a. DNA polymerases are the enzymes that form the DNA in cells. During DNA replication (copying), most DNA polymerases can "check their work" with each base they add. This process is called review. If the polymerase detects that you have added a wrong nucleotide (incorrectly paired), remove it and replace it immediately, before continuing with DNA synthesis

b. In homologous recombination, the information from the homologous chromosome that matches that of the damaged one (or from a sister chromatid if the DNA has been copied) is used to repair the fragmentation. In this process the two homologous chromosomes are approached and the undamaged region of the homologue or the chromatide is used as a template to replace the damaged region of the broken chromosome. Homologous recombination is "cleaner" than the union of non-homologous ends and does not usually cause 11 mutations

c. Excision repair: damage to one or a few DNA bases is usually fixed by removing (excising) and replacing the damaged region. In repair by base cleavage, only the damaged base is removed. In nucleotide excision repair, as in the mating repair we saw earlier, a nucleotide section is removed

Describe what the results would look like if the data supports your hypothesis.
Black_prince [1.1K]

Answer:

Please see below  

Explanation:

In such a case, the data will indicate a positive trend towards the outcome predicted in the dependent variable. However, the data has to show a significant difference (as indicated by p value) between the measured variables for it to be a valid support of the hypothesis.
