WGU BioChem OA Review withcomplete solution
Males and Females are equally affected - --ANSWER---
Autosomal
The process of copying DNA in the lab. - --ANSWER---
Polymerase Chain Reaction (PCR)
Template DNA, Nucleotides (dNTPS), DNA Polymerase,
and DNA Primers. - --ANSWER---What is needed for
Polymerase Chain Reaction?
Denaturing, Annealing, Elongating - --ANSWER---What
are the three steps of a Polymerase Chain Reaction
(PCR)?
,Denaturing (DNA is heated up to separate it) - --
ANSWER---What is the first step of a Polymerase Chain
Reaction?
Cooling the Polymerase Chain Reaction. Primers stick to
the DNA that you want to copy and ADD DNA
Polymerase - --ANSWER---What is Annealing?
The Polymerase Chain Reaction is heated and DNA
Polymerase adds nucleotides to build a new DNA strand. -
--ANSWER---What is elongating?
Ligase - --ANSWER---What is NOT involved in PCR?
It is used to repair damage to bases caused by harmful
molecules by removing the base that is damaged and
replacing it. #1 GLYCOSYLASES see the damaged
DNA. #2 DNA Polymerase puts the right one back #3
DNA Ligase seals it. - --ANSWER---What is base
excision repair (BER)?
, DNA Glycolysase sees the damage and removes it, DNA
polymerase puts the tight base back, DNA ligase seals it
back up. - --ANSWER---What are the 3 steps in base
excision repair?
1 - --ANSWER---How many nucleotides does base
excision repair remove?
Mismatch Repair (MMR). It is the only one to occur
during REPLICATION - DURING THE
PROOFREADING - --ANSWER---What is it called when
a large section of the nucleotide is removed from the
DNA so that DNA polymerase can try again? (This
corrects DNA damage)
Mismatch Repair (MMR) repairs errors such as G with T
instead of G with C. DNA Polymerase fixes it. This
happens during replication and MMR removes a large
section of the nucleotide from the DNA and DNA
Polymerase tries again. - --ANSWER---What repairs a
base mismatch?
