Biology [r]: The science of life — of complex, self-organizing, information-processing systems living in the past, present or future. ^[e]
Life [r]: Living systems, of which biologists seek the commonalities distinguishing them from non-living systems. ^[e]
Cell (biology) [r]: The basic unit of life, consisting of biochemical networks enclosed by a membrane. ^[e]
Genetics [r]: The study of the inheritance of characteristics, genes and DNA. ^[e]

Allele [r]: A specific sequence of a gene, and one of a pair in a diploid cell (one per chromosome). ^[e]

Transposon [r]: Blocks of conserved DNA that can occasionally move to different positions within the chromosomes of a cell. ^[e]
Transposons as a genetic tool [r]: Semi-parasitic DNA sequences which can replicate and spread through the host's genome. ^[e]

Gene duplication [r]: The incorporation of the same gene into different parts of the genome of an organism. ^[e]
Gene flow [r]: The movement of genetic alleles from one population to another. If there is a low gene flow between two populations they may become distinct species. ^[e]
Genetic engineering [r]: The process of manipulating genes, usually outside the organism's normal reproductive process. ^[e]
Genotype [r]: Genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms, based on a combination of alleles located on homologous chromosomes that determines a specific characteristic or trait. ^[e]

Transgenic plant [r]: Plants that have been genetically modified by inserting genes directly into a single plant cell, from a different species. ^[e]

Nucleic acid [r]: A class of macromolecules important in conveying genetic information. ^[e]
- DNA [r]: A macromolecule — chemically, a nucleic acid — that stores genetic information. ^[e]
- RNA [r]: A polymer, made using the nucleotides of adenosine, guanosine, uridine and cytidine, that is used for a variety of biological functions in living systems. ^[e]

Chromosome [r]: A compact body of ribonucleic acid wrapped around proteins that is the unit in which genetic material is distributed during cell division. ^[e]
Chromosome band [r]: A striped pattern observed on stained chromosomes. ^[e]

Endosymbiotic theory [r]: Theory on the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. ^[e]

Epigenetics [r]: Modifications in a gene's activity, expression, and/or regulation that do not involve changes to the DNA sequence. It is possible for such differences to be inherited from one generation to the next. ^[e]
Evolution [r]: Add brief definition or description
