A purine base, one member of the basepair A-T (Adenine and thymine)
A pyrimidine base that is the constituent of DNA and RNA involved in base pairing with guanine.
The molecule that encodes genetic information. It determines the structure, function and behaviour of the cell.
Cells containing a true nucleus bounded by a nuclear membrane.
A purine base that is an essential constituent of both RNA and DNA. One member of the basepair G-C (Guanine and Cytosine)
The basic building blocks of nucleic acids. They are made up of a nitrogen-containing base linked to a sugar and a phosphate group.
A polymeric compound consisting of many nucleotides.
Cells, like bacteria, that don't have a nuclear membrane so that the nuclear material is either scattered in the cytoplasm or collected in a nucleoid region.
A organism found in the upper respiratory tract, inflammatory exudates, and various body fluids of normal and/or diseased humans and, rarely, domestic animals. Otherwise known as strep.
A pyrimidine base that is an essential constituent of DNA. One member of the basepair A-T (Adenine and thymine)
Plants that, when self-pollinated, will create offspring similar to their parents in one or more traits.
