Chapter 13, Problem 26CONQ
Summary Introduction
To review:
The selection of start codons by eukaryotic ribosomes and the sequence in eukaryotic mRNA (messenger ribonucleic acid) that provides an optimal context for a start codon.
Introduction:
Translation is completed in three steps; initiation, elongation, and termination. At the time of initiation, a small ribosomal unit binds to the mRNA sequence. The amino acid is brought by charged tRNAs(transfer RNA) that are connected to each other, in order to form a polypeptide. Then, a stop codon in the mRNA terminates the process.
