Question

1. The replication of a complete genome in humans and some bacteria takes roughly the same amount of time, despite some major differences.

(a) The DNA of E. coli has approximately 4.6 x 10^6 base pairs (bp). If it can replicate at a rate of 1000 bp/s, how long would it take to replicate its genome?

(b) The DNA in a human cell has 3 x 10^9 bp and can replicate at a rate of 50 bp/s. If this was the overall replication rate, how long would it take to replicate a human genome? (c) In humans, this replication process actually takes less than an hour. Why is it much faster than you predicted?

2. Using a timeline, list the major experiments that led to the discovery of DNA as the molecule of heredity.
