DNA, Genes, and Chromosomes

Differentiate between terms and use them correctly in context
Understand that a gene is a short section of DNA that codes for a protein
Genes are located on specific loci on chromosomes
Alleles of genes lead to variation
A sequence of three DNA bases (triplet) codes for an amino acid
The genetic code is universal, non-overlapping, and degenerate
Understand the difference between an exon and an intron
The end product of a gene is a protein, which has implications if it changes.
