One of the questions early geneticists had to answer was how only four nucleotides can specify placement of 20 amino acids in pr

Answer:

<h2>Codon </h2>

Explanation:

The sequence of DNA is transcribed into mRNA, containing the sequence  for protein synthesis, protein is synthesized according to the codons in mRNA.  This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is  known as codons.

There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20  amino acids, and the remaining three  are stop codons.

These there codon do not code for any amino acid.

And these 61 codons, they  code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.

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.
