The Central Dogma of Molecular Biology:
- DNA directs RNA synthesis and RNA directs protein synthesis
Transcription:
- The DNA-directed synthesis of an RNA molecule
Translation:
- The RNA- directed synthesis of a protein
Why is the RNA intermediate needed?
- DNA can stay in the protected environment of the nucleus
- Gene expression can be amplified
- The RNA copies can be altered in different ways
- Gene expression can be further regulated
