WGU c785 2023 with all the correct
answers(Actual test 100% verified)
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
