WGU C785 UPDATED Exam Questions and
CORRECT Answers
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 proccess of copying a section of dna in
order to make proteins
DNA translation - CORRECT ANSWER - Process by which mRNA is converted into a
protein
non-template/coding strand - CORRECT ANSWER - its sequence matches the sequence
of the RNA that is transcribed from the template strand and codes for a polypeptide
