Question
3. The bacterium E.coli replicates it’s DNA from start to finish in one process.That is approximately four million nucleotides are replicated from the first
base to the last base in about 30 minutes. Homo traciensis has a genome of
four billion nucleotides. If both species copy their DNA at the same rate, we
would predict that H. traciensis would take 500 hours (1000/2) to replicate
its DNA. How long would it take to go from zygote to eight cell blastula?
a. 1500 h b. ½h c. 13h d. 5,000,000h e. 500h
please explain why!!
Explanation / Answer
To go from zygote to cell blastula you need to mitosis needs to occur 3 times. So, simply 3 replications * 500 = 1500 hours choice a
