There are four types of them;

• Adenine and Thymine are double H-Bonds.

• Guanine and Cytosine are triple H-Bonds.

Additional:

Other DifferencesbetweenDNA andRNA:

•DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.

• DNA is stable under alkaline conditions while RNA is unstable.

•DNA is responsible for storing and transferring genetic information while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.

Answer:

Some plants and fungi go through the asexual reproduction process. Mammals go through the process of sexual reproduction.

Explanation:

Asexual reproduction is the simplest way for one individual to give birth to another. In this type of reproduction, the next generation acquires the same characteristics that their parents have, since they receive equal copies of the DNA, that is, they are clones. In this one, there is no encounter of gametes nor fertilization. On the other hand, sexual reproduction consists in the union of the male and female gametes, forming the zygote that will give rise to a new being. It is through reproduction that genetic information is transmitted between generations. Each originated individual inherits the genetic material from his parents.
