Question

Explain translation of protein synthesis bio class 12 5 marks

Answer 1

The information required to build proteins resides on the DNA in the form of sequences of bases, and has the form of triplets of bases called "codons" following the genetic code. Once the genetic information describing how to build a protein is transcribed to RNA, it has to be "translated" into the "language" of the protein. The sequence of bases on the RNA forms a code for the amino acid building blocks of the protein. The word "translation" seems particularly appropriate for this process since the information contained in the DNA is translated from the four-character alphabet of the bases to the twenty-character alphabet of the amino acids.
