A nitrogenous base in DNA.

Nitrogen bases are

Nitrogenous base+sugar=____

The ratio of phosphates, sugars and nitrogen bases in ds-DNA

Assertion :- The backbone of polynucleotide chain is formed due to sugar and phosphate. Reason :- A nitrogenous base is linked to the pantose sugar through a N-glycosidic linkage to formed a nucleoside.

Pentose sugar binds with nitrogenous base by bond and with phosphate by bond to form nucleotide.

Glycosidic bonds exist in DNA molecule between (a) Sugar and phosphate (b) Any two nitrogen bases (c) Sugar and nitrogen base (d) Purines and pyrimidines

In DNA purine nitrogen bases are :-

If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence ?
