What do the different combinations of nucleotide bases (A, T, G, C) represent? (ex: CATGCAT = pointy ears)
The cell
They are random, why are we learning this?
The traits coded for by genes
ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases.

POINT MUTATION: a single point in the sequence is changed. For instance a G is changed to an A.
FRAMESHIFT MUTATION - a mutation that involves an addition or deletion, which results in a shift in the reading frame.
A SILENT MUTATION occurs when the nucleotide changes, but the resulting amino acid is the same.
A NONSENSE MUTATION occurs when a codon is changed to a STOP codon. If a codon is changed to STOP, the building of the amino acid terminates and the protein is incomplete.
Original DNA: CCC GGG
Mutated DNA: CGC GGG
What kind of mutation is this?
Point
Frameshift
Silent
Nonsense
