What is the difference between purines and pyrimidines?

Back

Purines (adenine and guanine) have a double-ring structure, while pyrimidines (cytosine, thymine, and uracil) have a single-ring structure.

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

What is the role of RNA?

Back

RNA plays a crucial role in protein synthesis and can also have functions in catalyzing biochemical reactions.

Front

What are the three types of RNA?

Back

The three types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information that guides the development and functioning of living organisms.

What are lipids and their main functions?

Back

Lipids are macromolecules that include fats, oils, and phospholipids. They are primarily used for energy storage, insulation, and making up cell membranes.

Front

What is a triglyceride?

Back

A triglyceride is a type of lipid formed from one glycerol molecule and three fatty acids, serving as a major form of energy storage in animals.
