Question

Which is correct about dna replication? dna polymerase can build dna from scratch. dna polymerase adds nucleotides in the 3' to 5' direction. the place where the parent dna becomes unzipped during dna replication is called the replication fork. dna is made conservatively. the strand made continuously is the lagging strand?

Answer 1

The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.

DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.

DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.

DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.

The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
