WGU BioChem OA Review with complete solution

Males and Females are equally affected Correct Answer-Autosomal The process of copying DNA in the lab. Correct Answer-Polymerase Chain Reaction (PCR) Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA Primers. Correct Answer-What is needed for Polymerase Chain Reaction? Denaturing, Annealing, Elongating Correct Answer-What are the three steps of a Polymerase Chain Reaction (PCR)? Denaturing (DNA is heated up to separate it) Correct Answer-What is the first step of a Polymerase Chain Reaction? Cooling the Polymerase Chain Reaction. Primers stick to the DNA that you want to copy and ADD DNA Polymerase Correct Answer-What is Annealing? The Polymerase Chain Reaction is heated and DNA Polymerase adds nucleotides to build a new DNA strand. Correct Answer-What is elongating? Ligase Correct Answer-What is NOT involved in PCR? It is used to repair damage to bases caused by harmful molecules by removing the base that is damaged and replacing it. #1 GLYCOSYLASES see the damaged DNA. #2 DNA Polymerase puts the right one back #3 DNA Ligase seals it. Correct Answer-What is base excision repair (BER)? DNA Glycolysase sees the damage and removes it, DNA polymerase puts the tight base back, DNA ligase seals it back up. Correct Answer-What are the 3 steps in base excision repair? 1 Correct Answer-How many nucleotides does base excision repair remove?
