Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is mutation?
A
A change in the DNA sequence, Can be a single nucleotide or a large chromosomal change to the DNA, Silent, missense, and nonsense are examples of these
B
This process is where peptide bonds are formed between amino acids
C
This process only opens a portion of the DNA called a gene
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -Substitution Substitution, as related to genomics, is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.

Detailed explanation-3: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.

Detailed explanation-4: -A mutation (Section 14.1) is a change in the nucleotide sequence of a short region of a genome (Figure 14.1A). Many mutations are point mutations that replace one nucleotide with another; others involve insertion or deletion of one or a few nucleotides.
