Question

The genome size of ___________ is approximately 5x10^6 bp and can be replicated in 30 minutes. The human genome size is 3x10^9 bp, about 600 × larger, and should take 300 hours (~13 days) to replicate based on the bacterial rate of replication. However, the entire human genome is replicated within a few hours because ___________.

a. E. coli; of advanced replication machinery
b. Yeast; of μltiple replication origins
c. Humans; of highly efficient polymerases
d. Bacteria; of siμltaneous replication at μltiple loci

Answer 1

The entire human genome is replicated within a few hours because of simultaneous replication at multiple loci.

Step-by-step explanation:

The genome size of E. coli is approximately 5x10^6 bp and can be replicated in 30 minutes. The human genome size is 3x10^9 bp, about 600 × larger, and should take 300 hours (~13 days) to replicate based on the bacterial rate of replication. However, the entire human genome is replicated within a few hours because of siμltaneous replication at μltiple loci. Bacteria have the ability to initiate replication at multiple sites simultaneously, which allows for faster replication of the genome.
