Which of the following must occur for a mismatch error to be repaired? Which is the best answer, I think it's A, am I right?
A)Damaged DNA must be identified by DNA repair proteins
B)The sequence of nucelotides in the damaged DNA sequence must guide the synthesis of the correct DNA sequence
C)Entire strands of damaged Dna must be destroyed by DNA eating enzymes within the nucleus.
I replied back saying that I've already used that and now I need someone to tell me if my answer is right or wrong.
Can you please tell me if my answer is right or wrong?
To determine the correct answer, let's break down the options and consider the process of DNA repair.
A) Damaged DNA must be identified by DNA repair proteins: This is a crucial step in the DNA repair process. When DNA is damaged, specialized proteins scan the DNA strands to identify any abnormalities or mismatches.
B) The sequence of nucleotides in the damaged DNA sequence must guide the synthesis of the correct DNA sequence: This option refers to the process of using the damaged DNA sequence as a template for the creation of the correct complementary DNA sequence. This is a key step in repairing the mismatch error.
C) Entire strands of damaged DNA must be destroyed by DNA eating enzymes within the nucleus: This option is incorrect. DNA eating enzymes, known as nucleases, are responsible for degrading DNA, but their role in DNA repair is not to destroy entire strands of damaged DNA. Instead, they assist in removing specific damaged regions or nucleotides.
Based on these explanations, the correct answer is B) The sequence of nucleotides in the damaged DNA sequence must guide the synthesis of the correct DNA sequence. This option correctly describes the process of using the damaged DNA as a template for the synthesis of the correct DNA sequence during DNA repair.
Therefore, if you thought the answer was A), it is not the most accurate answer. The best answer is B).
