Refer to Figure 3. Which substance is the enzyme?

An atom or molecule that has gained or lost electrons is defined as a(n):

In humans, aniridia, a type of blindness, is due to a dominant gene A.  Migraine headaches are due to another dominant gene M, which is on a different chromosome.  A man who suffers from both conditions (AaMm) marries a woman who suffers from both (AaMm). What are the chances of an offspring having both aniridia and migraine headaches?

Tall stem is dominant over dwarf stem in peas.  If a homozygous tall plant is crossed with dwarf plant, what will be the ratio of the offspring?

Identify Part I in Figure 5 below:

Use the Table provided to answer the following question: The DNA sequence ATC codes for the amino acid:  

How many carbon dioxide molecules are needed to make one glucose molecule?

 Assume that an incompletely dominant gene controls the feather color in chickens so that BB produces black, BW produces a slate-gray color called blue, and WW produces asplashed-white.  A second gene on a separate chromosome controls comb shape, with the dominant gene R producing a rose comb and the recessive genes rr producing a single comb. If a pure breeding black, rose-comb chicken is mated with a white, single-comb chicken, what proportion of the offspring will be white, single-comb chickens?

How many nucleotide bases in mRNA code for a single amino acid?

Which describes the function of DNA Polymerase III?
