Open Questions: Glossary of Life Sciences
- Amino acid
- B cell
- A type of organic molecule, certain examples of which occur
in the nucleotides of DNA and RNA. The bases which actually occur
are adenine, guanine, cytosine, thymine (DNA), and uracil (RNA).
- Crossing over
- The theory that eukaryotic cell organelles, such as mitochondria
and chloroplasts, originated as free-living bacteria which were
incorporated symbiotically into the earliest forms of eukaryotic
- Eukaryotic cell
- Expressed sequence tags
- G protein
- Germ line
- Hox gene
- Inclusive fitness
- Messenger RNA
- A simple organic molecule which is the basic unit of nucleic
acids (RNA and DNA). A nucleotide, in turn, consists of a sugar --
ribose (in RNA) or deoxyribose (DNA) -- plus a base plus a
phosphate group (PO4).
- Peptide nucleic acid
- Polymerase chain reaction
- Prokaryotic cell
- Promoter region
- A single-celled eukaryotic organism, such as an amoeba. A
member of the taxonomic kingdom called Protista.
- Restriction enzyme
- Reverse transcriptase
- RNA interference
- Single nucleotide polymorphism
- Stem cell
- Another name for the theory known as endosymbiosis.
- T cell
- Transcription factor
- A protein which activates or represses the expression of a gene.
- Transfer RNA
