WGU c785 BIOCHEMISTRY UNIT QUESTIONS AND ANSWERS (2023/2024) [GRADED A LATEST ] polymerase chain reaction (PCR) - CORRECT ANSWER process to copy DNA What is needed to complete PCR - CORRECT ANSWER Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA Steps of PCR - CORRECT ANSWER denaturation, annealing, elongation denaturation - CORRECT ANSWER loss of normal shape of a protein due to heat or other factor Annealing - CORRECT ANSWER cooled to 50c primers stick and want to copy and add DNA polymerase Elongation - CORRECT ANSWER reaction heated to 70C and DNA polymerase add nucleotides building a new DNA strand. base excision repair - CORRECT ANSWER a modified base is first excised and then the entire nucleotide is replaced DNA glycosylase - CORRECT ANSWER removes damaged DNA DNA polymerase - CORRECT ANSWER replaces to damaged DNA ligase seals it base excision repair - CORRECT ANSWER removes one single nucleotide MIsmatch repair - CORRECT ANSWER The cellular process that uses special enzymes to fix incorrectly paired nucleotides. What DNA damage is corrected by mismatch repair - CORRECT ANSWER errors in replication fixed What occurs when DNA polymerase binds to DNA to make RNA - CORRECT 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 - CORRECT ANSWER change in 1 nucleotide produces a STOP codon silent mutation - CORRECT ANSWER A mutation that changes a single nucleotide, but does not change the amino acid created. Missense - CORRECT ANSWER a mutation that changes one amino acid What happens during RNA splicing - CORRECT ANSWER after transcription, the introns are removed and the exons are hooks back together DNA transcription - CORRECT ANSWER the
