Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.
Gene editing involves the change of genotype
A single insertion or deletion of a nucleotide will basically lead to a frameshift mutation where the “reading frame” is disrupted. Normally, amino acids are encoded by three nucleotides, called a codon.
