what is heterozygous?
During replication, DNA makes an ________ copy of itself.
What is identical?
A criteria of cells that utilize a membrane bound nucleus to house DNA.
What are eukaryotic cells?
What percent of the offspring of a cross of heterozygous parents will be homozygous (AA - Aa)?
What is 50%?
The four nitrogen bases found in DNA.
What are adenine, guanine, cytosine, and thymine?
A model that shows possible gene combinations.
What is a Punnett square?
One of two or more forms of a particular gene
What is an allele?
genes of a trait that is hidden when the dominant gene is present

What is zero percent?
A single strand sequence of code used to build amino acid chains?
What is mRNA.

What is Meiosis?
A cell that contains a full set of chromosomes totaling a number of 46.
What is Diploid?
The changing of the structure of a gene.
What is a mutation?

What is Bb and BB?
The process of transcribing DNA to mRNA, which is read by tRNA in a ribosome to form a protein.
What is protein synthesis?
