Select The Best Answer.

A- Cellular function of protein synthesis is control by genes.
B- Deoxyribose, phosphoric acid & 4 nitrogenous bases are component of the cellular DNA.
C- Two purines Adenine & Thymine & two pyrimidines guanine & cytosine are DNA nitrogenous bases.
D- A & C is TRUE.
E- C is FALSE.

This is easy. The answer is B.

Thymine is not a purine, it's a pyrimidine. the same happens with guanine. so the answer is E.

bbbbbbbbbbbbbbbbbbbbbbbb

e is the ans

Remember to "CUT the pyramid"!

Pyrimidines = Cytosine Uracil Thymine

This is a simple:

B is true.. thats the basic composition of DNA. a Deoxyribose, phosphoric acid and amp, and the 4 nucleotide bases (A T C and G)


However, E is also correct in that C is FALSE!

Purines are Adenine and Guanine, while the Pyrimidines are Cytosine and Thymine.

I remember it like this: "PURINES!?!? AG! thats disgusting!!!"

Its silly i know.. but whatever works right!?

Hahahaha, P and urine, "AG! disgusting!"...works for me! Thanks for sharing, Kite.
