Bio Practice Exam 28 Questions with Verified Answers Why did DNA evolve to be the carrier of genetic information in cells as opposed to RNA? - CORRECT ANSWER the hydrogen at the 2' position in the deoxyribose of DNA makes it more stable than RNA In the mismatch repair process, enzyme complexes replace bases that were incorrectly inserted into the newly synthesized DNA strand. To function, they must be able to distinguish between the parent DNA strand and the new strand. How is this accomp...
