Which nitrogenous base is found in DNA, but not found in RNA?  

Which represents the products of the light-dependent reactions of photosynthesis? For what process are these products needed?

In tomato plants, purple stems (P) are dominant to green (p), and red fruit (R)  is dominant to yellow fruit (r). If a heterozygous purple-stemmed, red-fruited plant were self-fertilized, what proportion of the offspring would have green stems and yellow fruit?  

In peas, smooth seed coat is dominant over wrinkled.  What phenotypic ratio will occur if a heterozygous smooth seeded plant is self-fertilized?

What is a gamete cell?

Which is the largest?

If a body cell has 50 chromosomes as the diploid number, how many chromosomes would be in a gamete cell?

Imagine a protein is boiled and loses its 3-dimensional structure.  The unfolded protein cannot perform its function, so it is considered:

The reactants in photosynthesis are:
