CORNER OF THE RING IS BONDED TO AN H ATOM THE RING IS BONDED TO AN OH GROUP
3 TYPES OF RNA WHICH ARE mRNA,tRNA,&rRNA
1 TYPE OF DNA ONLY RNA CAN BE FOUND IN NUCLEUS OF CYTOPLASM.
DNA CAN BE FOUND IN NUCLEUS.

EXPLAIN HOW TO CALCULATE PERCENTAGE OF CYTOSINE IF DNA
MOLECULE CONTAINS 24% THYMINE

AMOUNT OF THYMINE = AMOUNT OF ADENINE AMOUNT OF CYTOSINE = AMOUNT OF GUANINE

24% + 24% = 48% ?=?

(CYTOSINE + GUANINE) + 48% = 100%
(CYTOSINE + GUANINE) = 100% - 48%

(CYTOSINE + GUANINE) = 52%

CYTOSINE = 52/2
=26%
