<em>The type of mutation that occurred would be base pair deletion.</em>
Base pair deletion mutation is a type of mutation involving the deletion of one or more nucleotide bases from a DNA/gene. This causes a reduction in the base pairs and shortens the length of the DNA/gene
<u>For example, if the first codon of a gene with base sequence 'AGGGCTACG' is deleted, the gene becomes shortened with a new base sequence of 'GCTACG'. Thus, the mutated gene would have a shorter base pair when compared to its wild-type counterpart.</u>
When exercising is when the lungs work the hardest because you're using a lot of muscles and are running around and are using force in your body so the lung works really hard to make sure the body gets enough air while working out.
