Vedclass · Answer

(B) The genetic code is defined by the sequence of nitrogenous bases in $mRNA$. In $mRNA$,the nitrogenous bases are Adenine $(A)$,Guanine $(G)$,Cytosine $(C)$,and Uracil $(U)$. Thymine $(T)$ is present in $DNA$ but is replaced by Uracil $(U)$ in $RNA$. Since the coding dictionary (genetic code) is based on the sequence of codons in $mRNA$,Thymine is absent in the coding dictionary.

Which of the following bases is absent in the coding dictionary?
