What Type of Mutation Is Inversion

Inversions are a special type of mutation in which a piece of chromosomal DNA is flipped 180 degrees. For an inversion to occur, two breaks occur in a chromosome, the region between the breaks gets inverted, and the ends of the region get rejoined to the rest of the chromosome.

Is inversion a block mutation?

Deletions – a portion of the chromosome is removed (along with any genes contained within this segment) Inversions – a segment of a chromosome is removed and then replaced within the chromosome in reverse order.

What is inversion in DNA mutation?

Inversions. An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of the chromosome breaks.
