Science / Genetics / Base Sequence: A partnership of organic bases found in dna and rna: adenine forms a base pair with thymine (or uracil) and guanine with cytosine in a double-stranded nucleic acid molecule. MORE
Science / Chemistry / Nucleotide: A molecule which is a basic building block of nucleic acids and which plays a key role in energy transfer in biochemical reactions. Nucleotides consist of a five-carbon sugar, a heterocyclic nitrogen- MORE
Science / Chemistry / Nucleotide Base: A heterocyclic nitrogen-containing base that is a constituent of nucleotides. Examples are adenine, guanine, thymine, uracil, and cytosine. MORE
Science / Biology / Thymine: One of the pyrimidine bases in DNA, thymine is replaced by uracil in RNA. MORE
Science / Biology / Pyrimidine: One of the groups of nitrogenous bases that are part of a nucleotide. Pyrimidines are single ringed, and consist of the bases thymine (in DNA), uracil (replacing thymine in RNA), and cytosine. MORE
Science / Biology / Ribonucleic Acid (RNA): Nucleic acid containing ribose sugar and the base Uracil; RNA functions in protein synthesis. The single starnded molecule transcribed from one strand of the DNA. There are three types of RNA, each is MORE
