Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in a tRNA
chubhunter [2.5K]

Answer:

Substitution

Explanation:

There are 3 types of mutations: deletions, insertions, and substitutions.

A deletion deletes one of the bases (AGTC), which can completely mess up the sequence and create a completely different protein.

An insertion inserts a new base into the strand, which can also completely mess up the sequence and create a completely different protein.

A substitution just changes one of the bases to a different base. This doesn't usually affect what protein is made, but when it does, it only changes one of the amino acids in the sequence, whereas the others change all of the amino acids in the sequence.

If the same protein is still created, then this person only experienced a substitution because it didn't affect the end result of the protein.

Why is acetylcholine broken down?
Aneli [31]

Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.

<h3>What is Acetylcholine?</h3>

Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.

Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.

In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
