People who have muscular dystrophy have something called a "mutation". How does that mutation arise

The correct answer is - It can occur when the DNA is copied over there can be a problem that is not caught during cell division causing that makes the new DNA mutated form of the original version and the mutation can be ok or harmful.

Explanation:

DMD or muscular dystrophy is a recessive x liked genetic disorder that takes place due to mutation or the error in the genes during cell division and desired protein does not form called dystrophin.

It takes place due to an error in DNA replication and is not corrected or identified by the checkpoints of the cell division and expressed from the mutated form of dystrophin which is shorter than the original form.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
