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.

<h2>Answer is "RuBisco"</h2>

Explanation:

  • It contains high measures of fundamental amino acids, which makes it somewhat interesting among vegetable proteins. Because of its properties, RuBisCo is a generally excellent possibility for food applications. It can not exclusively be utilized as a protein source yet in addition as an emulsifier, frothing and gelling operator
  • RuBisCO, and it is a type of protein, called an enzyme, that is involved in the Calvin cycle.An enzyme is a type of protein that makes reactions occur faster. For example, there is an enzyme in our body that helps transfer carbon dioxide from our cells to our blood. This reaction occurs 107 times faster with the enzyme
  • Hence, the right answer for fill up the blanks is "RuBisco"
