Small (2 – 9 base pairs) repeating sequences of DNA that do not code for a protein, and vary in the number of repeats in the human population.  Are used to create a DNA profile.

Which is a single stranded piece of DNA that binds near an short tandem repeat (STR) locus and extended by Taq DNA polymerase to make complementary DNA strands in a polymerase chain reaction (PCR).

This type of eukaryotic gene expression control involves DNA methylation and histone acetylation which affect chromatin remodeling, which controls access to genes.

Feather color in chickens is incompletely dominant so that BB produces black, BW produces blue, and WW produces a splashed white.  If a chicken with blue feathers is mated with another chicken with blue feathers, what will be the phenotypic ratio of the offspring?  

There are two steps to protein coding gene expression: Step 1 is __________ and Step 2 is _____________.

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?

If one strand of DNA has the base sequence ATCGTT, the complementary strand of that DNA must have the base sequence:

The reactants in photosynthesis are:
