PLEASE HELP MEEEE
why is methionine always the first amino acid? (please use your own words and don't make your answer too long)


Sagot :

Synthesis of a protein starts with the binding of ribosomal subunits and initiation factors to the mRNA. In this process, the initiation factor eIF2 is bound to initiator tRNA (met-tRNAi) and not to other tRNAs. Upon recognition of the initiation codon AUG, translation starts with the methionine that is bound to the initiator tRNA.

sorry girl it has to be long
