TRANSLATION

TRANSLATION Translation means that genetic information copied into RNA with transcription is converted to a protein or polypeptide chain. In other words, it is the expression of genetic information in the form of protein molecules. Three important components of protein synthesis are messenger RNA (mRNA), transfer RNA (tRNA) and ribosomes. mRNA includes a code (password) which determines the protein’s amino acid sequence. The mRNA unit that encodes an amino acid and comprises three nucleotides is called codon. When the translation of mRNA starts, codons are read as successively without a space and hesitation. Each codon indicates either one aminoacid participating in protein synthesis or the termnation of protein synthesis. Code defines three nucleotide sequences called as codon and the relationship between aminoacids .The 61 codons are codons encoding amino acids, they are also called sense codons . Degeneracy of the genetic code gives the meaning that aminoacids can be determined by m...
