The human genome contains about 3 billion base pairs. During the first cell division after fertilization of a human embryo, S ph
Nataly [62]

Answer:

5556

Explanation:

If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.

However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.

5556 molecules of DNA polymerases acting on 5556  origins of replication are needed.

(ii)   A gas that bubbles out a solution.
(iii)  A precipitate.
