A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
human-biology× 2027
for questions about the general biological features of human beings (as opposed to the biology of non-humans).
genetics× 1817
the branch of biology that deals with the transmission and variation of inherited characteristics.
evolution× 1715
Changes in the heritable attributes of populations of organisms over time. The mechanisms of evolution are mutation, migration, drift, and selection.
biochemistry× 1540
The study of chemistry within the scope of biology: the compounds that occur and the reactions involving them in living organisms.
species-identification× 1363
Questions looking to find the name of a specific organism. Please include as much information as possible on location/habitat, size/characteristics and behavior. Ideally, you should provide images.
cell-biology× 1209
The study of cells, their physiological properties, structure, environmental interaction, division, life cycle, and death, as well as the organelles they contain. Also known as cytology.
neuroscience× 1035
The study of the structure and function of the nervous system and its components.
botany× 1033
The study of plant life; e.g. angiosperms, gymnosperms, bryophytes, pteridophytes, and algae.
dna× 965
the carrier of genetic information, including for all known living organisms. The only known exceptions are RNA viruses.
entomology× 851
The scientific study of Insecta. If the question is about some other group of arthropod use 'arthropod' tag.
bioinformatics× 839
The science of collecting and analyzing complex biological data such as genetic codes using informatics.
physiology× 757
The study of the normal function of living organisms and the means by which it is achieved.
microbiology× 669
the study of extremely small organisms. This includes organisms like bacteria, fungi, protozoa, and viruses.
proteins× 663
Biopolymers consisting of amino acids that fold into 3D shapes and perform a large number of functions in living organisms.
immunology× 490
The study of the immune system in organisms, primarily responsible for fighting infection.
homework× 481
indicates that the question is likely based on a home assignment in biology-related university or high school courses or is about an elementary concept that may seem trivial to biology profes…
molecular-genetics× 477
The scientific study of the structure and function of genes at the molecular level, particularly chromosomes and DNA.
human-anatomy× 417
for questions about the general anatomical features of human beings as opposed to the anatomy of non-human animals.
ecology× 408
Interactions and relationships among organisms and their environment. This includes biotic and abiotic (non-living/environmental) factors that impact organisms.
brain× 407
The primary component of the central nervous system, which, along with the spinal cord, controls the body of bilaterally symmetrical beings.
metabolism× 403
the set of defined biochemical transformations occuring within the cells of living organisms.
neurophysiology× 376
The study of the physiology of the nervous system, with emphasis on transcellular communication, and cellular and molecular processes involved in neural communication.
terminology× 337
used or the meaning of words as used in scientific literature. Questions should ideally include a link or quote as context for where the term was encountered.
cancer× 335
A malignant group of uncontrollably dividing cells that form a tumour. Questions regarding (proto)oncogenes and tumour-suppressor genes should also use this tag.
pharmacology× 313
the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function
dna-sequencing× 290
Technique(s) by which the sequence of DNA is obtained. The principles are similar for [tag:rna-sequencing].
gene-expression× 287
The process by which information encoded in a gene is converted into a functional protein or RNA, resulting in or contributing to a phenotype.
lab-techniques× 286
Questions relating to protocols, procedures, and good practice when using laboratory equipment.
enzymes× 280
globular proteins that catalyse a biochemical reaction, increasing the overall rate by reducing activation energy. Most chemical reactions in a cell need enzymes in order to occur at rates…
