Detailed explanation-1: -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-2: -A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

Detailed explanation-3: -A gene mutation (myoo-TAY-shun) is a change in one or more genes. Some mutations can lead to genetic disorders or illnesses.

Detailed explanation-4: -Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.

Detailed explanation-5: -Hello students, our next topic for the MCQ is ‘Mutations’. The mutation is the abrupt changes to the genetic material of organism. The mutational changes affect DNA or sometimes whole chromosome. The types of mutation are genetic mutation and chromosomal mutation. The result of mutation produces altered protein.
