Question

Semiconservative replication implies that Group of answer choices

A) Each of the new double stranded DNA molecules contains one of the original intact strands and one completely new strand.
B) One of the new double stranded DNA molecules contains both of the original strands, while the other contains two new strands.
C) Each of the new double stranded DNA molecules contains strands that are composed of segments of original and newly synthesized material.
D) None of these.

Answer 1

A. Each of the new double stranded DNA molecules contains one of the original intact strands and one completely new strand.

Step-by-step explanation:

DNA replication is a semi-conservative process. During DNA replication, the two parental DNA strands are separated to serve as the template. DNA polymerase extends the RNA primers by the addition of the deoxynucleotides complementary to the sequence of the template DNA strand.

After replication of complete length of template DNA, two DNA double helices are formed. Each of the new DNA double helices contains one parental template strand and one newly formed DNA strand. This is why the process is called to be semi-conservative.
