Introduction

A gene is a genetic molecule that is passed down from one generation (parents) to the next (offspring). A gene is a coding area of DNA that contains instructions for protein synthesis.

RNA is a transcription product of DNA.

The 3 major types of RNA found in a cell include:

mRNA (Messenger RNA)
rRNA (Ribosomal RNA)
tRNA (Transfer RNA)

mRNA is a single-stranded RNA molecule derived from a gene during transcription that occurs in the nucleus. Then mRNA exits the nucleus and enters the cytoplasm in order to form proteins through translation.
