The tRNA anticodons are complementary to the cod â¦ ons (three nucleotide sequence that represents an amino acid) on mRNA and allow them to be identified by the ribosome. In detail, translation is the second process of making a protein or polypeptide, the first being transcription.
The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residues in a protein is defined by the sequence of a gene, which is encoded in the genetic code. In general, the genetic code specifies 20 standard amino acids; however, in certain organisms the genetic code can include selenocysteine andâin certain archaeaâpyrrolysine.
DNA codes for mRNA and mRNA is then translated by ribosomes to protein (Central Dogma, http://en.wikipedia.org/wiki/Central_dog... So as Roland said, option a & b are almost same. I'm gonna say A. By the way, DNA also codes for functional RNA molecules but that's something else.
