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