Mutations can be...
Harmful
Beneficial
Neutral
All of the Above
A substitution mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
An insertion/additon mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
A deletion mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
This is considered the most harmful type of gene mutation. It occurs when the codon reading frame is shifted and creates a chain reaction of errors in amino acids.
