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...

Replication of DNA begins at a single origin of replication and then proceeds the entire length of the strand, in one direction (T/F) - correct answer False What enzyme is responsible for relieving the stress associated with the twisting and untwisting of a DNA strand during replication. - correct answer Topoisomerase As a replicated DNA strand elongates, what enzyme is responsible for adding nucleotides? - correct answer ...

DNA - ANSWER-Double stranded polynucleotide formed from two separate chains of covalently linked deoxyribonucleic units. It serves as the cell's store of genetic information that is transmitted from generation to generation. Double Helix - ANSWER-The typical structure of a DNA molecule in which the two complementary polynucleotide strands are wound around each other with base pairing between the strands. Base Pair - ANSWER-Two complementary nucleotides in an RNA or DNA molecule that are h...
