Question

Which of the following describes what happens during mismatch repair of DNA? Enzymes identify the newly synthesized DNA strand, remove a segment surrounding the mismatched nucleotides, and resynthesize the DNA segment correctly. o Enzymes copy the correct DNA sequence from the DNA in another cell, import the DNA sequence, and use the imported DNA sequence to repair the mismatched nucleotides. Enzymes cut out both strands of DNA containing the mismatched sequence, copy the same sequence from the homologous chromosome, and insert the copied sequence. Q Enzymes identify the newly copied DNA strand, delete the mismatched nucleotide, pull the gap closed, and join the nucleotides on either side of the gap together

Explanation / Answer

During the mismatch repair sequence, enzymes get to copy the correct DNA sequence from the other cell and after that they import the DNA and repair.

Therefore (b) Enzymes, copy the correct DNAsequence from the DNA in anothercell import the DNA sequence and use the imported DNA sequence to repair the mismatched nucleotides.
