Are Minor Bases and Nucleosides the Same Thing

Click For Summary
SUMMARY

Minor bases and nucleosides are not the same, although minor base nucleosides exist. Minor bases refer to nucleobases that are not adenine, guanine, cytosine, thymine, or uracil, which are the primary bases found in DNA and RNA. A nucleoside is formed when a nucleobase is attached to a sugar, specifically ribose for RNA and deoxyribose for DNA. The combination of a nucleoside with a phosphate group results in a nucleotide, which is essential for nucleic acid polymerization.

PREREQUISITES
  • Understanding of nucleobases and their roles in DNA and RNA

NEXT STEPS
  • Research the different types of minor bases in biochemistry
  • Study the structure and function of nucleosides and nucleotides
  • Explore the role of ribose and deoxyribose in nucleic acid formation
  • Learn about the polymerization process of nucleic acids
USEFUL FOR

Students and professionals in biochemistry, molecular biology researchers, and anyone interested in the structural components 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.
