Mutations in the genetic code can occur when

the dna is carried from the nucleus to the ribosome

dna duplicates and an amino acid is changed

amino acids are transported from the cytoplasm to ribosomes

the cell divides in to daughter cells

The correct answer is option the cell divides in to daughter cells.

Explanation:

The mutation is the alteration or change in the sequence nitrogenous bases of DNA.

Mutation in DNA generally occurs by base substitution, insertion or deletion of nucleotide base pairs during the process of DNA replication, which takes place during S-phase of cell division.

Mutations in DNA are corrected by DNA proofreading mechanisms of enzyme DNA polymerase.

Thus, the cell divides into daughter cells is the correct answer.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
