A mutation is a disadvantage.

A mutation happens by chance.

Mutations are sometimes inheritable.

Specific mutations can become more common through natural selection.

the insertion of a nucleotide into DNA

the placement of ribosomes within the endoplasmic reticulum

transcription of RNA in the nucleus

the release of messenger RNA from DNA

transformation

deletion

insertion

duplication

a mutation

crossing over

polyploidy

a meiosis error

all of these

by random chance during replication

through contact with chemicals

mutagens in the environment

natural processes that affect genetic diversity

natural processes that always change phenotype

unnatural processes that only change genotype

unnatural processes that harm genetic diversity

at one or a few nucleotides in a gene sequence

across an entire gene sequence

throughout the chromosome

throughout the genome

an egg cell

a nerve cell

a muscle cell

a brain cell

a "deletion" type of mutation would occur

the resulting organism would die because it wouldn't have enough DNA

the resulting organism would be harmed

an "inversion" type of mutation would occur

a mutation

transcription

regeneration

translation
