(a) If the haploid human genome contains 3 × 109nucleotide pairs and the average molecular weight of a nucleotidepair is 660, how many copies of the human genome are present, onaverage, in 1 mg of human DNA?
(b) What is the weight of one copy of the human genome?
(c) If the haploidgenome of the small plant Arabidopsis thaliana contains7.7 × 107 nucleotide pairs, how many copies of the A.thaliana genome are present, on average, in 1 mg of A.thaliana DNA?
(d) What is the weight of one copy of the A. thaliana genome?
