Explanation:
Detailed explanation-1: -Genome editing is a way of making specific changes to the DNA of a cell or organism. An enzyme cuts the DNA at a specific sequence, and when this is repaired by the cell a change or ‘edit’ is made to the sequence.
Detailed explanation-2: -A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term.
Detailed explanation-3: -Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
