Vedclass · Answer

(C) In $DNA$,the nitrogenous bases are Adenine $(A)$,Guanine $(G)$,Cytosine $(C)$,and Thymine $(T)$.Nucleotides are formed by the combination of a nitrogenous base,a pentose sugar (deoxyribose in $DNA$),and a phosphate group.$AMP$ stands for Adenosine monophosphate,$CMP$ for Cytidine monophosphate,and $GMP$ for Guanosine monophosphate,which are all valid nucleotides found in $DNA$ or $RNA$.$TMP$ stands for Thymidine monophosphate. In $DNA$,the nucleotide containing Thymine is specifically called Deoxythymidine monophosphate $(dTMP)$.Since $DNA$ contains deoxyribose sugar,the term $TMP$ is technically incorrect as it implies the presence of ribose sugar (as in $RNA$),where Thymine is replaced by Uracil $(U)$. Therefore,$TMP$ is not a standard structure found in $DNA$ nomenclature.
