The RNA base pairs Adenine pairs with Uracil. Thus, option D is correct.
The basic composition of nucleic acid (DNA and RNA) is deoxy ribose sugar or ribose sugar attached to phosphate group and one of four nitrogenous base two purines (Adenine and guanine) and two pyrimidines (cytosine and thymine).
DNA (Deoxy ribonucleic acid) is a self-replicating material that is present in all living organisms as the basic component of chromosomes. It is the carrier of genetic information.
DNA is a double-helix , a spiral consisting of two DNA strands wound around each other. The two strands are antiparallel to each other. The structure of DNA was discovered by James Watson and Francis Crick in 1953.
In DNA adenine form two hydrogen bond with thymine where as cytosine form three hydrogen bond guanine.
In case of RNA (Ribonucleic acid) instead of thymine, uracil is present. Thus, adenine pairs with Uracil. Hence, option D is correct.
