As fast as … polymerase.
How much time is needed to double the entire genome of a mammal? For DNA polymerase in a cell line of a hamster’s ovary, it’s around 18 hours! The average replication speed of this enzyme is about 600-1200 bases per minute …
Helloo? do we have a bricklayer here who can lay 1000 bricks in a minute? Or someone who can pack 1000 products in 60 seconds?
It really is an impressive speed, while also maintaining excellent accuracy. Let’s appreciate our polymerases, they do a splendid good job.
