Read the below Statements about the structure of genetic material and identify the correct ones.
I. Adenine and guanine are bases that have a double ring structure , cytosine, thymine and uracil are based with a single ring structure .
II. An adenine nucleotide from DNA is the same as an adenine nucleotide from RNA , DNA adenine pairs with uracil and RNA adenine pairs with thymine.
III. The base pairing that occurs in a double DNA helix and when RNA is synthesised during transcription follows the rule that a purine pairs with a pyrimidine.
IV. The two Polynucleotides on a DNA molecule run in opposite directions so that the double helix formed has two strands that are anti-parallel to each other.
