Nitrogen Bases in DNA.
What are GCAT?
100
Is made up of three nitrogen bases.
What is a codon?
100
A change in the DNA.
What is a mutation?
100
A Tall (TT) plant is crossed with a Tall plant (Tt). What percent of the offspring will be tall?
100%
100
Type of mutation that removes nitrogen bases.
What is a deletion mutation?
200
Aid in replication by "unzipping" DNA and pairing the nitrogen bases.
What are enzymes?
200
Travels to the nucleus, copies the DNA and then travels to the cytoplasm to a ribosome.
What is mRNA?
200
A chart that shows all of the possible combinations of alleles that can result from a genetic cross.
What is a punnett square?
200
A homozygote white flower is crossed with a heterozygote purple flower. What percent of the offspring will be white?
50%
200
The study of heredity.
What is genetics?

300
A purebred smooth pea plant is crossed with a homozygote wrinkled pea plant. What percent of the offspring will be homozygote smooth?
0%
300
Organisms that for many generations have had the same trait.
What is a purebred?
400
This scientists helped Francis Crick and James Watson with the discovery of the structure of DNA.
Who is Rosalind Franklin?
400
This molecule transfers amino acids to the ribosome.
What is tRNA?
