- Adrenergic beta-antagonist : Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.
- Allozymes : Enzymes that are coded for by different alleles at the same locus.
- Atenolol : A cardioselective adrenergic beta-antagonist medication for hypertension and angina pectoris.
- Biogenic amine receptor : Cell surface proteins that bind biogenic amines with high affinity and regulate intracellular signals which influence the behavior of cells.
- Biology : The science of life — of complex, self-organizing, information-processing systems living in the past, present or future.
- Bisoprolol : Cardioselective beta-1-adrenergic blocker, used in the management of hypertension and angina pectoris.
- Cat : A feline, particularly the domesticated feline, Felis catus, a small carnivorous mammal.
- Clopidogrel : A platelet aggregation inhibitor used to prevent cardiac events
- DNA : A macromolecule — chemically, a nucleic acid — that stores genetic information.
- Dihybrid cross : A cross in genetics between two individuals identically heterozygous at two loci, for example, AaBb x AaBb.
- Drug toxicity : Manifestations of the adverse effects of drugs administered therapeutically or in the course of diagnostic techniques.
- Evolution : A change over time in the proportions of individual organisms differing genetically.
- Gene flow : 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.
- Genetics : The study of the inheritance of characteristics, genes and DNA.
- Genotype : 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.
- Heterosis : An observable phenomenon in which hybrid plants or animals may exhibit greater yields, health or faster rate of growth than their inbred parents.
- Horizontal gene transfer in prokaryotes : Horizontal gene transfer (HGT; also called lateral gene transfer, LGT) is defined as movement of genes between different species, or across broad taxonomic categories. Prokaryotes are cells, such as bacteria, that do not have a nucleus enclosed by a nuclear membrae. Their DNA is in a region of the cell called the nucleiod, or nucleus-like material.
- Horizontal gene transfer : Transfer of genetic material to a being other than one of the donor's offspring.
- Lactose intolerance : Due to a decrease of the lactase enzyme in cells lining the small intestine of adults and a concomitant inability to break down or metabolize lactose.
- List of biology topics : Add brief definition or description
- Maine Coon : The oldest American breed of long-haired domestic cat.
- Metoprolol : An adrenergic beta-antagonist useful in angina pectoris, hypertension, or cardiac arrhythmias.
- Microsatellite : Polymorphic loci present in nuclear and organellar DNA that consist of repeating units of 1-6 base pairs in length.
- Mutation : Changes to the DNA sequence that cause new genetic variation.
- Natural selection : The differential survival and/or reproduction of classes of entities that differ in one or more characteristics
- Preoperative care : Preparation and management of a patient prior to surgery.
- Single-nucleotide polymorphism : A DNA sequence variation across chromosomes within an individual or a species, involving only a single base change.
- Targeted gene replacement : Technique in which cloned DNA is introduced into mammalian stem cell culture, via gene modification in vitro.
