Step by step
Solved in 2 steps
- What percentage of the DNA in the genome actually corresponds to genes? How much is actually protein-coding exons? What makes up the rest?What is recombination? Mention its applications with reference to genetic engineering.Suppose that E. coli synthesizes DNA at a rate of 100,000 nucleotides per minute and takes 40 minutes to replicate its chromosome. (a) How many base pairs are present in the entire E. coli chromosome? (b) What is the physical length of the chromosome in its helical configuration—that is, what is the circumference of the chromosome if it were opened into a circle?
