The genetic codes of arginine are:
$CGU , CGC , CGA$
$CAU , CAC , CAA$
$AGU , AGC , AAC$
$GAU , GAC , GAA$
In a cell, protein synthesis occurs by the linking together of amino acids. The base sequence of $mRNA$ defines the primary structure of proteins because
Assertion : $UAA,\,UAG$ and $UGA$ terminate protein synthesis.
Reason : They are not recognised by $tRNA$.
Match the codons given incolumn $I$ with their respective amino acids given in column $II$ and choose the correct answer.
column $I$ (Codons) | column $II$ (Amino acids) |
$(A)$ $UUU$ | $(I)$ Serine |
$(B)$ $GGG$ | $(II)$ Methionine |
$(C)$ $UCU$ | $(III)$ Phenylalanine |
$(D)$ $CCC$ | $(IV)$ Glycine |
$(E)$ $AUG$ | $(V)$ Proline |
Which of the following is not a property of the genetic code?
Which one of the following pairs is correctly matched with regard to the codon and the amino acid coded by it
