What is a nucleotide?

The video tutorial explains nucleotides, their structure, and their role in forming nucleic acids like DNA and RNA. It covers the components of nucleotides, including the sugar molecule, phosphate group, and nitrogenous base. The video also discusses the pairing of nucleobases and the differences between purine and pyrimidine bases. Additionally, it highlights the functions of nucleotides, such as energy transfer through ATP and their role as cofactors in cellular processes.

Differentiate between purine and pyrimidine bases.
