Another player in translation…. .The ribosome Interacts w/ proteins to form 2 main ribosomal subunits. Large subunit Small subunit (Subunits come together to facilitate interaction between tRNA and mRNA. A site – Acceptor or aminoacyl-tRNA site. P site – Peptidyl site. E site – Exit site. rRNA’s and protiens mRNA tRNA’s Polypeptide (protiein) tRNA carrying an amino ac Holds tRNA with polypeptide chain Small subunit
