Answer to Question #286425 in Molecular Biology for Oliver

Question

2

nd diagram: Show how the leading strand (at least 8 nucleotides long) undergoes

replication. Make sure to show specific nucleotides (show at least 20 nucleotides on

the parent of the complementary leading strand).

● Label the polarity of both strands.

● Indicate direction of replication fork and direction of leading strand replication.

● Include all enzymes involved in the replication of this leading strand. Make sure to

indicate in your drawing where the enzyme(s) would be working on the DNA

molecule.

Answer 1

Within each fork, one DNA strand, called the leading strand, is replicated continuously in the same direction as the moving fork, while the other (lagging) strand is replicated in the opposite direction in the form of short Okazaki fragments.
