- Protein synthesis
- Translation
- tRNA is free to collect another amino acid
- Complement-ary bases of tRNA pair with the bases on the mRNA strand
- Amino acids that are close together are joined to make an amino acid chain
- This a polypeptide
- tRNA molecules bring amino acids to the ribosome.
- The amino acid attached to each tRNA molecule depends on the order of bases in the tRNA
- Every protein is formed from a specific number of amino acids in a particular order
- The order of the bases in the DNA defines the order in which the amino acids are joined together
- One section of DNA codes for one particular protein
- Ribosome moves along the mRNA in this direction reading one codon at a time
- A codon is a triplet of bases
- Transcription
- Section of DNA unwound - 2 strands separate
- Free complement-ary bases pair with open bases
- Free bases join to make mRNA
- In mRNA, T is replaced with U
- Translation
