A  partial DNA template has the following sequence of nucleotide bases: A-C-G-T-A-C Type the nucleotide bases for the corresponding mRNA strand.

Hydrolysis of the N-glycosyl bond between deoxyribose and a purine base in DNA creates an apurinic (AP) site. An AP site is more thermodynamically destabilizing to a DNA molecule than is a mismatched base pair. Examine the structure of an AP site. H₂N HN N O™ -O-P-O-CH₂ Guanine H₂N N HN Select the chemical consequences that could contribute to DNA instability at AP sites. H H 1₂0/ H fewer hydrogen bonds between the unpaired pyrimidine base and water disruption of the base-stacking interactions decreased interaction between the mutated DNA strand and histones increased ability of the deoxyribose ring to open without the attachment of the purine base H H Guanosine residue (in DNA) O™ -O-P-O-CH₂ O H H H O Apurinic residue H OH H

Draw and label a diagram showing four DNA nucleotides, linked together in two strands. PLEASE DRAW ON PAPER
