Question

Which of the following nucleic acid complexes would undergo correction by the DNA mismatch repair system?

1) DNA-DNA duplex
2) DNA-RNA duplex
3) DNA-DNA triplex
4) DNA-RNA triplex

Answer 1

The DNA mismatch repair system corrects errors in DNA replication and recombination. It recognizes and repairs nucleotide mismatches in the newly synthesized DNA strand. The DNA-DNA duplex would undergo correction by the DNA mismatch repair system.

Step-by-step explanation:

The DNA mismatch repair system corrects errors that occur during DNA replication and recombination. It recognizes and repairs nucleotide mismatches in the newly synthesized DNA strand. Therefore, the nucleic acid complex that would undergo correction by the DNA mismatch repair system is the DNA-DNA duplex (option 1).
