Question

DNA replication is a process that involves copying the DNA molecule. If a single base was miscopied, what would be a possible result of this for the cell in which it happened? (4 points)

A. All the proteins the cell creates from the miscopied strand will do different jobs than the old ones.
B. If the new sequence codes for the same amino acid as the original cell, it will function normally.
C. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.
D. Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.

Answer 1

Answer:

C. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.

Explanation:

If a single base is miscopied during replication then there is a possibility that the new base which has been incorporated will specify the same amino acid just like the old base. It happens because genetic code is degenerate which means that more than one codon can specify same amino acid.
