$NHC$ structural proteins are
Basic proteins rich in lysine, arginine
Regulatory proteins
Catalytic proteins rich in tryptophan and arginine
Required for packaging of chromatin at higher levels
It is absent in $RNA$.
Watson and Crick are known for their discovery that $DNA$
Group the following as nitrogenous bases and nucleosides:
Adenine, Cytidine, Thymine, Guanosine, Uracil and Cytosine.
Nucleic acids exhibit secondary structure. Describe through Watson-Crick model.
In sea urchin $DNA$, which is double stranded, $17\%$ of the bases were shown to be cytosine.The percentages of the other three basesexpected to be present in this $DNA$ are
