Answer to Question #286424 in Molecular Biology for Oliver

Question

1

st diagram: Show your original double stranded DNA molecule with specific

nucleotides (show at least 20 nucleotides per strand).

● Include the necessary enzyme(s) required to initiate replication.

● Make sure you indicate in your drawing where the enzyme(s) would be working

on the DNA molecule.

● Label the polarity of both strands.

Answer 1

DNA polymerase can only add nucleotides to an existing chain.Since the two DNA strands run antiparallel the leading strand is replicated continuously due to it having its 3' end toward the replication fork, while the lagging strands 3' end is pointed away from the replication fork.
