What do you mean by protien Synthesis

Which enzymes helps in charging og tRNA

Which codon is called initiation codon

What do you mean by StopCodon

What are the role of Ribosomes

Initiation of protien Synthesis

Bacterial Ribosome

Eukaryotic Ribosomes

Ribosomes

Initiator Factors

Steps of Initiation of prokaryotes

mRNA binds to the small subunit of the ribosome

Intiator tRNA binds to the mRNA through base pairing between the codon and anticodon

Steps of Initiation on Eukaryotes
