The two new DNA molecules formed in replication ________.
A)are different from the original DNA
B)both contain only two new daughter DNA strands
C)both contain only the parent DNA strands
D)contain one parent and one daughter strand
E)are identical,with one containing both parent strands,and the other containing both daughter strands

Question

Quizplus · Accepted Answer

The two new DNA molecules formed in replication contain one parent and one daughter strand. Each new DNA molecule consists of one original (parent) strand and one new (daughter) strand. This is known as semi-conservative replication. Option A is incorrect because the new DNA molecules are identical in base sequence to the original DNA, except for the introduction of occasional mutations or errors during replication. Option B is incorrect because each new DNA molecule consists of one parent and one daughter strand. Option C is incorrect because both new DNA molecules contain at least one daughter strand. Option E is incorrect because this option is not possible in semi-conservative DNA replication.
