When the messenger RNA gets information (codon) from the DNA, it comes toward the ribosomes where transfer RNA also attached. At the ribosomes, the transfer RNA decodes the information of messenger RNA as match its anticodons with codons of messenger RNA. (Nucleotides as A with U and C with G). This process of decoding at the ribosomes with the help of transfer RNA called the translation process which ultimately leads the process toward releasing of long chain peptide.
