It is discovered that a chromosome from the cells of a particular organism is made up of a strand of DNA that is 500 base pairs long. If 30% of the DNA molecule is determined to be made up of adenine, how many of the bases would you expect to be guanine?
What will be an ideal response?
200; 1000 total bases (500 x 2); 30% = 300 adenine molecules; A = T = another 300 of the bases; 40% (or 400 bases) that remain are cytosine and guanine; if C = G, then guanine = 200.
