Detailed explanation-1: -In translation, polypeptides are synthesized using mRNA sequences and cellular machinery, including tRNAs that match mRNA codons to specific amino acids and ribosomes composed of RNA and proteins that catalyze the reaction. The genetic code is degenerate in that several mRNA codons code for the same amino acids.

Detailed explanation-2: -Translation involves a complex cellular organelle, the ribosome, which together with a number of accessory factors reads the code in a mRNA molecule and produces the appropriate polypeptide235. The ribosome is the site of polypeptide synthesis.

Detailed explanation-3: -The steps in translation are: The ribosome binds to mRNA at a specific area. The ribosome starts matching tRNA anticodon sequences to the mRNA codon sequence. Each time a new tRNA comes into the ribosome, the amino acid that it was carrying gets added to the elongating polypeptide chain.
