An example of a frame shift mutation that removes a 1-4 bases from the sequence? Question 22 options: inversion deletion translocation addition substitution

The correct answer is "deletion".

A frame shift mutation that removes 1-4 bases from the sequence is a deletion. This type of mutation occurs when one or more nucleotides are removed from a gene sequence. This can cause the reading frame of the gene to shift, leading to the production of a different protein or even stopping protein production altogether.

Here's a step-by-step explanation:

1. A gene sequence is made up of a series of nucleotides.

2. In a deletion mutation, one or more of these nucleotides are removed.

3. This removal causes the reading frame of the gene to shift. The reading frame is the way the gene's sequence is divided into groups of three nucleotides, each of which codes for a specific amino acid.

4. This shift in the reading frame changes the sequence of amino acids that are coded for by the gene.

5. As a result, a different protein may be produced, or protein production may stop altogether.

The other options listed - inversion, translocation, addition, and substitution - are also types of mutations, but they do not involve the removal of bases from the sequence. Instead, they involve rearranging, adding, or replacing bases.
