Hemophilia Pedigree - Father has hemophilia, mother does not. What is the outcome for their kids? -
correct answer ✔✔His daughters would be carriers. This is x-link recessive.
Autosomal:
Dominant: - correct answer ✔✔Autosomal: males and females equally affected.
Dominant: non-carrier parents
polymerase chain reaction (PCR) - correct answer ✔✔The process of copying DNA in the lab. Uses
Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA primers.
3 Steps of PCR - correct answer ✔✔1. Denaturation: DNA is heated to 95C to separate it.
2. Annealing: reaction is cooled to 50C; primers stick to the DNA you want to copy and add
DNA polymerase.
3. Elongation: reaction heated to 70C and DNA polymerase, adding nucleotides building a new
DNA strand.
Base Excision Repair (BER) - correct answer ✔✔How you repair a mutation. BER is used to repair damage
to a base caused by harmful molecules. You remove the base that is damaged and replace it. *BER
removes a single nucleotide*
DNA glycolsylase - sees damaged DNA and removes it.
DNA polymerase-puts the right one back in while DNA ligase seals it.
Mismatch repair (MMR) occurs during: - correct answer ✔✔replication. DNA polymerase proofreads
but sometimes a mismatch pair gets through. MMR removes a large section of the nucleotides from the
new DNA and DNA polymerase tries again. (Ex: C-T instead of C-A)
Mismatch Repair corrects what kind of DNA damage? - correct answer ✔✔When a base is mismatched
due to errors in replication. Such as G-T instead of G-C. DNA polymerase comes by and fixes it.
