Biology
1 answer:
Aleksandr-060686 [28]3 years ago
6 0

Answer:True

Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :

1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing

2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.

In a nucleotide, which would change based on the genetic code of the organism?
Setler79 [48]

Answer:

The correct answer is nitrogen base

Explanation:

The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.

       As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.

  In simple words change in single nitrogen base of a codon will change the entire codon.
