WebtRNAs bind to mRNAs inside of a protein-and-RNA structure called the ribosome. As tRNAs enter slots in the ribosome and bind to codons, their amino acids are linked to the growing polypeptide chain in a chemical reaction. The end result is a polypeptide whose amino … The signal peptide that sends a protein into the endoplasmic reticulum during … Transcription uses one of the two exposed DNA strands as a template; this strand is … WebJun 8, 2024 · The initiator tRNA, called Met-tRNA i, carries unmodified methionine in eukaryotes, not fMet, but it is distinct from other cellular Met-tRNAs in that it can bind eIFs and it can bind at the ribosome P site. The eukaryotic pre-initiation complex then recognizes the 7-methylguanosine cap at the 5′ end of a mRNA.
