<span>After release into the synaptic cleft, neurotransmitters interact with receptor proteins on the membrane of the postsynaptic cell,
causing ionic channels on the membrane to either open or close. When
these channels open, depolarization occurs, resulting in the initiation
of another action potential</span>
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.

Answer:
Cells help our body in many ways. if we didnt have cells out bodys would not function. Cells actually provide structure for the body and take in nutrients from food. They then convert those nutrients into energy, and carry out specialized functions.
