Introduction to RNA
- Helps in gene expression.
- Specify the amino acid sequence of a functional protein.
- Carries information from DNA to ribosome.
- Process of forming mRNA on a DNA template is called transcription.
Note:
a) If mRNA code for only one polypeptide : Monocistronic ( In Eukaryotes).
b) If mRNA code for two or more than two polypeptides : Polycistronic
