Which rna base pairs with the adenine in dna?
a. thymine
b. guanine
c. cytosine
d. uracil

The answer is D. uracil.

Interactions between nucleobases occur through the complementarity of nucleobases. In the DNA, base complements are A-T (adenine - thymine) and G-C (guanine - cytosine). In the RNA, base complements are A-U (adenine - uracil) and G-C (guanine - cytosine). Hence, only DNA contains thymine, while in RNA uracil is present instead of thymine

The RNA base pairs that pairs with the Adenine base in RNA is Uracil.

Further ExplanationNucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.DNA DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.Additionally, it carries the information that is used to make proteins which performs various functions in living cells.Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine. RNARibonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.
