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.

3. What is the difference between saponifiable and nonsaponifiable lipids?
lara [203]

Answer:

the difference is that unsaponifiable lipids do not contain fatty acids at least not as a component of the fundamental structure whereas saponifiable lipids do have fatty acids.

Explanation:

As a further explanation unsaponifiable lipids are lipids that do not contain fatty acids as components of the fundamental structure. On the other hand, complex also known as saponifiable lipids do contain fatty acids, and those fatty acids can be released in a process called saponification which is caused by alkaline hydrolysis.
