Which of the following statements about mutations is false? view available hint(s) which of the following statements about mutations is false? an addition mutation results in an added base in the dna sequence. a knock-out mutation results in a total absence of the mutated protein. a deletion mutation results in the loss of a base in the dna sequence. addition and deletion mutations disrupt the primary structure of proteins.

The correct answer will be option- A knock-out mutation results in a total absence of the mutated protein

Explanation:

A mutation refers to the change in the sequence of nucleotide in the DNA which could prove beneficial or harmful to the organism.

There are many mechanisms by which mutation is introduced in the gene which could be by:

1. Addition of nitrogenous bases in the DNA called addition mutation.

2. Deletion of nitrogenous bases in the DNA which leads to the loss of bases called deletion mutation.

3. The addition and deletion of the bases in the gene can disrupt the primary structure of the protein like in sickle cell anaemia.

4. The elimination or replacement of a gene by man-made technique is known as knockout mutation.

Since knockout mutation does not lead to the loss of mutated proteins, therefore, the option is the correct answer.
