This document provides a comprehensive and easy-to-understand overview of gene expression—the process by which genetic information in DNA is transformed into functional proteins. It explains each stage of this journey, from transcription and RNA splicing in the nucleus to translation at the ribosome. Students will learn how different types of RNA (mRNA, tRNA, and rRNA) collaborate to convert genetic code into a protein structure, and how this process underpins all cellular functions. Ideal for...
