True about genetic code except: (PGI June 2009)
Ans: B (Overlapping) & C (Ambiguous) The genetic code is specific (unambiguous), universal, degenerate, nonoverlapping & commaless.Charactemtlc-of Genetic Codespecificity: The genetic code is specificQ (unambiguous) i,e. a particular codon always codes for the same amino acid.universality: The genetic code is virtually universal i.e. the specificity of the genetic code has been conserved from very early stages of evolution with only slight differences in the manner in which the code is translated.degeneracy: The genetic code is degenerate (sometimes called redundant) Although each codon corresponds to a single amino acid, a given amino acid may have more than one triplet coding for it.Nonoverlapping & commaless: The genetic code is nonoverlapping & commutes, i.e. the code is read from a fixed starting point as a continuous sequence of bases, taken three at a time.Not punctuated
