Heredity B/Designer Genes C Question Marathon

[rtunnel97]

thats correct, your turn!

[Gemma W]

What's the difference between purines and pyramidines in terms of chemical structure & which is which?

[doge]

Adenine and guanine are purines which have 2 rings and 4 atoms of nitrogen.
Cytosine, thymine, and uracil are pyrimidines which have 1 ring and 2 atoms of nitrogen.

[Gemma W]

Right. Your turn

[SWAnG]

It's been a while since a question's been asked, so I thought I'd just ask a question! What is the purpose and special property of Taq polymerase in PCR?

[heidi456]

Taq polymerase is used in PCR to synthesize new DNA templates. It is a thermostable DNA polymerase which enables the PCR cycles to heat the solution up to 60c with out inactivation.

[SWAnG]

Yep your turn!

[heidi456]

Alright,
Q1: what is the inheritance pattern of mitochondrial DNA?

Q2: Mitochondrial DNA is more susceptible to damage from what, and for what reason?

[SWAnG]

Mitochondrial DNA is inherited through the mother.

mtDNA is particularly susceptible to reactive oxygen species generated by the respiratory chain due to its proximity.
