Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.

The correct answer is -

1) point mutation

2) deletion

3) inversion

4) frameshift mutation.

Explanation:

Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.

Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.

When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.

If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.

the correct answer is b
