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.

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.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
