Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
StMary's a good day for me and you are the kids going ❤️❤️ a good time☺️☺️
<span>The circulatory, immune, skeletal, excretory, muscular, endocrine, digestive, nervous and respiratory. those are the eight systems of the human body.</span>
A nucleotide or a nucleic acid either one :)
Lysosomes are organelles that break down waste material so they clean up waste basically so the body system that has the closest function to lysosomes is the excretory system
