1. You have a sample of DNA, and you measure the amount of adenine present at 21%. Based on this, the percentages of the other three nitrogenous bases must be ______. Group of answer choices thymine 21% A. uracil 21% B. guanine 29% C. guanine 21% D. cytosine 29% E. cytosine 21%
Added by Edward L.
Step 1
Step 1: Since adenine pairs with thymine and cytosine pairs with guanine, if adenine is present at 21%, then thymine must also be present at 21%. Show more…
