Question

Indicate the steps of eukaryotic DNA replication in order, from when a germ cell enters gap 1 (G1) phase to the cell cycle termination.

a. RNA primers are added to provide a 3 end for elongation.
b. RNA is replaced with DNA and lagging strands are joined,
c. Prereplication complex forms at one of many origins of replication.
d. DNA polymerase synthesizes both the leading and lagging strands from 5' to 3'.
e. Active telomerase can extend the lost telomere region.
f. The initiation complex creates an active replication fork as helicase unwinds DNA.

Answer 1

Step-by-step explanation:

1. Prereplication complex forms at one of many origins of replication.

2. The initiation complex creates an active replication fork as helicase unwinds DNA.

3. RNA primers are added to provide a 3 end for elongation.

4. DNA polymerase synthesizes both the leading and lagging strands from 5' to 3'.

5. RNA is replaced with DNA and lagging strands are joined.

6. Active telomerase can extend the lost telomere region.

All these process are the steps involved in the replication of DNA. The replication of DNA involves the biological production of two identical copies of DNA from one original DNA molecule. This is a very important biological process of life as it is involved in the inheritance pattern of life. It is essential in that the 2 daughter cells formed must contain the same sets of chromosome as the original parent.
