Question

The DNA strand growing toward the replication fork grows ____ in a 5'->3' direction as the replication for advances and is called the ____.

Answer 1

The DNA strand growing toward the replication fork grows continuously in a 5'->3' direction as the replication fork advances and is called the leading strand. The other strand, complementary to the 5' to 3' parental DNA, is extended away from the replication fork in small fragments known as Okazaki fragments, called the lagging strand.

Step-by-step explanation:

The DNA strand growing toward the replication fork grows continuously in a 5'->3' direction as the replication fork advances and is called the leading strand.

The other strand, complementary to the 5' to 3' parental DNA, is extended away from the replication fork, in small fragments known as Okazaki fragments, each requiring a primer to start the synthesis. These fragments are named after the Japanese scientist who first discovered them and are called the lagging strand.
