WebDNA polymerases add nucleotides only to the free 3 primed end of a growing strand of DNA therefore a new DNA strand can elongate only in the 5 to 3 primed direction … WebVerified answer. biology. The human genome contains about 3 billion base pairs. During the first cell division after fertilization of a human embryo, S phase is approximately 3 hours long. Assuming an average DNA polymerase rate of 50 nucleotides/sec over the entire S phase, what is the minimum number of origins of replication you would expect ...
