Hemophilia Pedigree - His daughters would be carriers. This is x-link
Father has hemophilia, recessive.

the outcome for their
kids?
Autosomal: Autosomal: males and females equally affected.
Dominant: Dominant: non-carrier parents
The process of copying DNA in the lab. Uses
polymerase chain reaction
Template DNA, Nucleotides (dNTPS), DNA
(PCR)
Polymerase, and DNA primers.
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
3 Steps of PCR polymerase.
3. Elongation: reaction heated to 70C and DNA

strand.
, 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
Base Excision Repair (BER)
DNA glycolsylase - sees damaged DNA and removes
it.
DNA polymerase-puts the right one back in while
DNA ligase seals it.

sometimes a mismatch pair gets through. MMR
Mismatch repair (MMR)
removes a large section of the nucleotides from the

Mismatch Repair corrects When a base is mismatched due to errors in
