Answer:

The correct answer will be option-B

Explanation:

A hydrogen bond is a weak bond formed between the two hydrogen atoms.

The tRNA is made up of a single strand of RNA which attains a 3D configuration and form a hydrogen bond between the two nucleotide base pairs.

The hydrogen bond is present in the tRNA stems and associated loops which contains modified bases like pseudouridine and inosine, thus hydrogen bond stabilizes the structure of the tRNA.

Thus, Option-B is the correct answer.

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.

Explain <br> "I don't need to know everything; I just need to know where to find it, when I need it.

son4ous [18]

When referring to knowing where to find something when you need it you mean that you do not need a memorization of all things, you just need a source to find it when in need. I hope this answer suited your needs.
