melting temperature
After spending too much time in the sun, a human male acquires
a mutation in the DNA in one of his skin cells. What is the
chance that this mutation will be passed to his offspring? Correct

Alternative splicing allows an organism to have a greater
________ than its ______ would suggest. Correct Answers

Ammonium thioglycolate is a common reducing agent in hair
treatment. The action of ammonium thioglycolate is to _____
the type of stabilizing force in the keratin in your hair called
______ Correct Answers break; disulfide linkages
An enzyme is experimentally saturated with substrate and the
enzyme's Vmax is calculated. The enzyme is then treated with a
large amount of inhibitor, causing the rate of product formation
to approach (but not reach) zero. As the substrate concentration
is gradually increased, the rate of product formation increases
until it eventually reaches the original Vmax. From these
observations, the inhibitor is most likely _______________.
Correct Answers competitive

thymine. What percentage of that organism's DNA would be
guanine? Correct Answers 33%
