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.

How is an agglutination reaction different from a precipitin reaction?
meriva

Cells clump together during a process called agglutination as a result of the accumulation of antigens and antibodies.

Immune complexes are created when soluble antigens are brought together by the appropriate antibody molecules, and they become visible when they are big enough to precipitate out of the solution.

  • The interaction between antibody molecules and the associated antigen molecules causes both agglutination and precipitation processes.
  • Agglutination, on the other hand, is the clumping of cells that occurs when one antibody binds several antigens at once.
  • Contrarily, precipitation occurs when soluble antigens and soluble antibodies interact to form a clear, insoluble substance known as the precipitate.
  • Agglutination takes place when a target antigen, also known as isoagglutinin, interacts with a corresponding antibody in the presence of an electrolyte at the right temperature and pH, leading to the development of apparent clumps or aggregates.
  • Precipitation happens when an electrolyte, an antigen, and a soluble antigen interact at the right temperature and pH to create cross-links or precipitates that sink to the bottom of the solution.
