<h2>DNA Fingerprinting</h2>
Explanation:
- DNA fingerprinting is a process in which samples of DNA are taken from evidence left at a crime scene and then are matched with samples of DNA taken from suspects. Often, perpetrators of crime leave some kind of physical evidence at the crime scene, such as saliva, hair, blood, or semen. DNA samples can often be collected from this and can then be compared with those who are suspected of committing the crime
- It allows us to identify an individual from biological samples. It's called fingerprinting because, just like identifying an individual based on the unique patterns we find on their fingers, we identify an individual based on the unique fingerprint of their DNA
- DNA fingerprints assist police due to their ability to identify individuals by their genetic markers. It is both a highly consistent and accurate form

Answer:
The answer is "ligand-gated channel".
Explanation:
The action that is described in the question is an example of a "ligand-gated channel".
The ligand-gated channels are found in the muscles and they are membranes made out of ion-channel proteins which chan be controlled by certain released chemicals into the medium to open them up or closed them and allowing the sodium, potassium or calcium ions to pass through.
I hope this answer helps.
