WGU C785 Biochemistry Unit Exam Questions And Answers( Top score A+) polymerase chain reaction (PCR) - ANSWER ==process to copy DNA What is needed to complete PCR - ANSWER ==Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA Steps of PCR - ANSWER ==denaturation, annealing, elongation denaturation - ANSWER ==loss of normal shape of a protein due to heat or other factor Annealing - ANSWER ==cooled to 50c primers stick and want to copy and add DNA polymerase Elongation - ANSWER ==reaction heated to 70C and DNA polymerase add nucleotides building a new DNA strand. base excision repair - ANSWER ==a modified base is first excised and then the entire nucleotide is replaced DNA glycosylase - ANSWER ==removes damaged DNA DNA polymerase - ANSWER ==replaces to damaged DNA ligase seals it base excision repair - ANSWER ==removes one single nucleotide MIsmatch repair - ANSWER ==The cellular process that uses special enzymes to fix incorrectly paired nucleotides. What DNA damage is corrected by mismatch repair - ANSWER ==errors in replication fixed What occurs when DNA polymerase binds to DNA to make RNA - ANSWER ==transcription ! DNA polymerase takes the individual nucleotides and matches the them to the parental sequences to ensure a correct pair. It must bind with RNA primer to work. nonsense - ANSWER ==change in 1 nucleotide produces a STOP codon
