A question about nucleic acids

In summary, minor bases and nucleosides can be the same thing because minor base nucleosides exist. However, the term "minor base" simply refers to nucleobases other than the main ones found in DNA and RNA. A nucleoside is formed when a nucleobase is bound to a sugar, while a nucleotide includes a phosphate group in addition to the nucleoside. This process leads to the formation of nucleic acids.

Wiki has a stack on this, plus you have a decent biochem textbook?

In brief:

There are minor base nucleosides. So, in a fashion, they can be the same thing.

Otherwise: No.

"Minor base" simply refers to the fact that the nucleobase isn't adenine, guanine, cytosine, thymine, or uracil. Other purines and pyrimidines occur in the body, but to a much lower extent than the main ones you find in DNA and RNA.

A nucleoside is what you get when you bind a nucleobase to a sugar (ribose in the case of RNA and deoxyribose in the case of DNA). And a nucleotide is what happens when that nucleoside is bound to a phosphate group. The polymerization of this phosphate/sugar backbone gives you nucleic acids.

1. What are nucleic acids?

Nucleic acids are biological macromolecules that are essential for the storage, transmission, and expression of genetic information in all living organisms. They are made up of long chains of nucleotides, which are composed of a sugar, a phosphate group, and a nitrogenous base.

2. What are the two types of nucleic acids?

The two types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA is responsible for storing and transmitting genetic information, while RNA is involved in the process of protein synthesis.

3. How are nucleic acids formed?

Nucleic acids are formed through a process called polymerization, in which nucleotides are joined together by covalent bonds to create long chains. This process is catalyzed by enzymes and occurs within the cells of living organisms.

4. What is the role of nucleic acids in the body?

Nucleic acids play a crucial role in the body, as they are responsible for storing and transmitting genetic information from one generation to the next. They also play a role in protein synthesis, which is essential for the functioning of cells and tissues.

5. How do nucleic acids differ from other biomolecules?

Nucleic acids differ from other biomolecules in terms of their structure and function. Unlike proteins, carbohydrates, and lipids, which are primarily involved in energy storage and structural support, nucleic acids are specifically involved in the storage and expression of genetic information.
