Understand that DNA is composed of sequences of nucleotides, which are the basic building blocks of DNA.
Recognize that a gene is a specific sequence of nucleotides in DNA that contains the necessary information to produce a functional product, typically a protein.
Differentiate between the terms: an allele is a variant form of a gene, a chromosome is a structure that contains many genes, and a nucleotide is a single unit of DNA.
Identify that the term 'gene' is used to describe a segment of DNA that codes for a protein.
