B
Explanation:
The structure of the mitochondrion is key to the process of aerobic (in the presence of oxygen) cellular respiration, especially the Krebs cycle and electron transport.
The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.
A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.
Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.
DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.
