If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme
erastovalidia [21]

Answer:

See the answer below

Explanation:

<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>

<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs)
ch4aika [34]

<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.
