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.
Answer:
Protecting Biodiversity: Biodiversity Hotspots About half of all plant and animal spp. ... If Earth has 150,100,000 sq km of land, how much land area is included in hot spots 0.1 x 0.157 = 0.0157 0.0157 x 150,100,000 = 2,356,570 sq. km.
