Answer: The correct answer is A. During this time, cells take in nutrients, which are important for energy, growth, and repair of the cell.

Interphase is the first phase of the cell cycle. During this phase, the cell takes in nutrients, which are important for energy, growth, and repair of the cell.  

In other words, cell prepares for division by growth, synthesizing essential proteins, and duplicating the DNA. This phase occurs prior to cell division.

This phase is primarily divided into G1, S, and G2 phase. G1 and G2 are the gap phases during which cellular growth and synthesis of essential proteins take place.

S phase ( synthesis phase) includes the duplication of the DNA so two identical cells are obtained after cell division.

Thus, the correct statement, which describes the interphase is A.

What role does the MutL protein play in DNA repair? (5 POINTS) It performs a proofreading function, similar to DNA polymerase, a
Zinaida [17]

Answer:

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

Explanation:

Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.

The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
