Thymine dimers can be repaired by Photoreactivation Repair or Nucleotide Excision Repair. - true or false?
Aleksandr-060686 [28]

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.

Lorico [155]

Answer:

d. T

For a given DNA sequence, the array is represented as:

5'ATCCTGGACACTGTACCATCGGTACCAATCACAGGTCCTTACAGT 3'

And the premier; 5' GGACCTGTGA 3' attaches to the complementary base on the DNA sequence.

i.e.

5'ATCCTGGACACTGTACCATCGGTACCAATCACAGGTCCTTACAGT 3'

*AGTGTCCAGG

Which of the following statements is true of ribosomes?
Delvig [45]

Answer: A) They are the site of protein synthesis.

Explanation:

Ribosomes are small round organelles attached to the endoplasmic reticulum in cells, and serve as site of protein synthesis. This is possible because the transfer RNA assembles amino acids to form polypeptide chains right in the ribosomes.

Thus, ribosomes are site of protein synthesis
