Genes may encode proteins or functional RNA molecules.
Their expression is regulated.

Alleles occupy the same locus on homologous chromosomes.
They may produce different trait variants.

Genotype refers to allele combinations.
Phenotype results from genotype and environment.

Phenotype includes structural, biochemical, and behavioral traits.
It is influenced by genes and environment.

Chemistry examines what matter is made of and how it behaves.
It also studies energy changes accompanying chemical processes.

Matter includes solids, liquids, gases, and plasma.
It is composed of atoms, molecules, or ions.

An element cannot be broken down chemically into simpler substances.
Each element is identified by its atomic number.

Compounds have definite formulas and characteristic properties.
Their components can be separated only by chemical means.

Mixture components retain much of their individual identity.
They can often be separated by physical methods.

The genetic code is read in triplets.
Each codon has a defined meaning.

The anticodon pairs with the codon during translation.
This ensures delivery of the correct amino acid.

AUG codes for methionine and usually serves as the start codon.
It establishes the reading frame.
