Hi there,
The process is called Transcription (mRNA) which is messenger RNA. It occurs in the nucleus of the cell. However, after being copied the RNA leaves the nucleus. Hope it helps.
<span>Because of semi-conservative replication in DNA synthesis, One of the strands of the new DNA molecule is original and one of the strands of the molecule is composed of new nucleic acids.</span>
The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.
