An AS Biology lesson covering transcription and translation in detail. It shows how an mRNA copy of a gene is made by RNA polymerase, how tRNA collects amino acids, and how ribosomes read codons to build a polypeptide, ending with the rough endoplasmic reticulum.
What this presentation covers
- an overview of protein synthesis
- transcription and RNA polymerase
- mRNA leaving the nucleus
- tRNA and amino acids
- translation at the ribosome, codon by codon
- stop codons and the finished polypeptide
- the rough endoplasmic reticulum and ribosomes
