The type of bonds between nitrogen bases in the DNA molecule.
What are hydrogen bonds?
400
Enzyme responsible for unwinding DNA and breaking hydrogen bonds between nitrogen bases.
What is DNA Helicase?
400
A pea plant is homozygous recessive for flower color (P) and heterozygous for seed color (Y) would have this genotype.
What is ppYy?

The three components of a DNA nucleotide.
What are the phosphate group, deoxyribose (5 carbon sugar) and nitrogen bases?
500
The enzyme responsible for adding corresponding nucleotides to the exposed DNA strand during replication.
What is DNA Polymerase?
500
Three reasons that pea plants are good for genetic experiments.
What are:
1. Compact, fast growing, mature quickly
2. Many different observable forms of the plant
3. Plant mating can be easily controlled
500
The three parts of the cell theory.
What are:
1. All living things are made of one or more cells
2. Cells are the basic unit of structure and function in organisms
3. All cells arise from existing cells
