Key concepts
3 concepts
- 1
The central dogma, developed by Francis Crick, explains how DNA contains genes that code for specific proteins.
- 2
During transcription, RNA polymerase copies a gene from DNA into messenger RNA (mRNA) inside the nucleus.
- 3
In translation, the ribosome reads the mRNA codons, and transfer RNA (tRNA) brings the corresponding amino acids to build a polypeptide chain, forming a protein.
