Bioinformatics: Genomics: Different Types of RNAs

RNAs are macromolecules which plays a major and necessary role in biology, they play a role of intermediary between DNA and Proteines .

RNAs can fold to secondary and even tertiary structures.

The main purpose to study RNAs in bioinformatics is to try to predict their structures, to know better about their interactions and their stability.

You can read about RNA structures in this post HERE.

RNAs have 2 main types:

1- Coding RNAs: Corresponding to mRNA (Messenger RNA) that plays a role of a transmitter, which transmits information from RNA and deliver it to Protein.

2- Non coding RNAs: Like rRNA (Ribosomal RNA), tRNA (Transfer RNA), snRNA...etc



mRNA : messenger RNA.
rRNA : ribosomal RNA.
tRNA : transfer RNA.
snRNA : (small nuclear) .
snoRNA : (small nucleolar ) .
scRNA : small cytoplasmic RNA.
tmRNA : transfer-messenger RNA.
siARN : small interfering RNA.
