DNA and RNA, both are types of nucleic acids. Figure out the correct statements concerning DNA and RNA from below. I. Adenine and guanine are bases that have a double ring structure; cytosine, thymine and uracil are bases with a single ring structure. II. An adenine nucleotide from DNA is the same as an adenine nucleotide from RNA; in DNA, adenine pairs with thymine and in RNA adenine pairs with uracil. III. The base pairing occurs in a double DNA helix and when RNA is synthesised during transcription it follows the rule that a purine pairs with a pyrimidine. IV. The two polynucleotide strands of a DNA molecule run in opposite directions so that the double helix formed has two strands that are parallel to each other.
