If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

Answer:

Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.

Explanation:

In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.

These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.

These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations

It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.

a Bb guinea pig crosses a Bb guinea pig, and four offspring are produced. All of the offspring are black. Explain how this could
boyakko [2]
There is a 100% chance of this happening.

Explanation :

By bringing the Upper case ‘B’ s down and across into the punnet square, we can already see that they are all going to have the same output/answer. If Bb represents Black and bb represents, say, brown, Bb would be shown in every square. Therefore, it would be a 100% chance of the Guinea pigs being black.
