What are the necessary components for binding of the amino acid to tRNA
- AA
- tRNA
- Aminoacyl-tRNa synthetase
- ATP
What does aminoacyl-tRNA synthetase do

attaches amino acids to tRNA
What are the components required for initation
- mRNA
- fMet-tRNA (bacteria)
- 30Sribosomal subunit
- 50S Ribsomoal subunit
- If-1
- IF-2
- If-3
What does If1 do

dissociation of large and small subunits of ribosome
IF2

Binds GTP delvers fMet (tRNA ) to intiation codon
IF3

binds 30S subunit and prevents association with 50S subunit
Elongation components
- 70 S intitation complex
- Charged tRNA
- Elongation factor Tu
- Elongation factor G
- GTP
- Peptidyl tranferase
Peptydly transferase

creates peptide bond between amino acids in A site and P site
Termination

RElease factor 1, 2, 3,
