Cell cycle checkpoints are control mechanisms in eukaryotic cells which ensure proper division of the cell.
Do you think that a cell must also transcribe its entire gene into RNA to pass this checkpoint? Explain. No, because RNA is not being used as a template to get the exact copy of the gene, the point of the RNA is to carry DNA instructions, so it doesn't have to transcribe its entire gene into RNA to pass the checkpoint.
