Nitrogenous bases

Vedclass · Answer

(A) The $DNA$ molecule consists of a sugar-phosphate backbone and nitrogenous bases. While the sugar (deoxyribose) and the phosphate group are identical in all $DNA$ molecules,the sequence of nitrogenous bases ($Adenine$,$Thymine$,$Guanine$,and $Cytosine$) varies significantly among different organisms. This specific sequence of nitrogenous bases acts as the genetic code,which determines the biological characteristics of an organism. Therefore,the variation in $DNA$ is primarily due to the sequence of nitrogenous bases.

The variation in $DNA$ among different organisms is due to the sequence of:
