Summary Introduction
Replication, transcription, and translation are important processes of the central dogma of biology. In translation, the mRNA molecule is translated into a protein sequence (amino acids). The mRNA, tRNA, and ribosome are three important components of translation machinery. Initiation, elongation, and termination are major steps involved in translation. Proteins play important roles in the structure and function of cells.

What are start codons and stop codons? Why is it important forthe ribosome to read “in frame”?
According to wobble rules, what codons should be recognized by the following anticodons? What amino acid residues do these correspond to?(a) 5′ ¬ICC ¬ 3′ (b) 5′ ¬GCU ¬3′
How does placement of a ribosome at the start codon differ in bacteria and eukaryotes? What role do the 59 cap and 39 poly-A tail play in this process in eukaryotes?
