Which of the following statements about DNA synthesis at the replication fork of a replicating DNA molecule is FALSE?

Select one:

a. One of the two new strands must be synthesized in fragments because the two strands have opposite directionality.

b. More than one of the other answer choices is false.

c. The sequence of each newly synthesized single strand is identical to that of the parental single strand that served as its template.

d. Double-stranded DNA synthesis requires both deoxyribonucleotides and ribonucleotides.

e. Nucleotides are added at the 3’ ends of all new strands in a replicating DNA molecule.

1. Which of the following statements about DNA synthesis at the replication fork of a replicating DNA molecule is FALSE?

c. The sequence of each newly synthesized single strand is identical to that of the parental single strand that served as its template.

this statement is false as newly synthesized single strands sequence is not identical to parental strand but it is complementary to the parental strands.

The following are the correct options.

a. One of the two new strands must be synthesized in fragments because the two strands have opposite directionality.

d. Double-stranded DNA synthesis requires both deoxyribonucleotides and ribonucleotides.

e. Nucleotides are added at the 3’ ends of all new strands in a replicating DNA molecule.
