Questions relating to how the field of biology has developed over time.

The eukaryotic process characterized by replication of nuclear DNA and formation of a second identical nucleus. Separate from cytokinesis.

Single nucleotide polymorphisms, or SNPs, are differences between two sequences of DNA at one individual nucleotide location.
× 21
the process of protein synthesis. The information encoded in the mRNA is translated into an amino acid sequence through the joint activity of tRNAs and ribosomes.
× 21
the doctrine of prevention, diagnosis and treatment of diseases and injuries in humans and animals.
× 20
produced during transcription before it leaves the nucleus to be be translated by a ribosome. This produces a sequence of nucleic acids for which mRNA is considered the template.

Questions relating to the binding of proteins to each other and other molecules.
× 20
a field of biology which utilizes biological systems like microorganisms to produce valuable products, such as biofuels, drugs, and vaccines.
× 19
Biologically-synthesized chemicals (or their derivatives) that cause growth suppression or death of bacteria. Other anti-microbials are often also considered under the class antibiotics these days.
× 19
The scientific study of behaviour and of the mind.
× 19
the mechanism by which a disease is causing the disease. For bacteria this can be the secretion of a toxin which is toxic for the host.
× 19
Questions requesting a reference (book, journal article, etc) for a specific topic/finding.
× 19
a polyphyletic group of unicellular fungi. Usually the term yeast is used synonymously with baker's yeast - Saccharomyces cerevisiae.
× 18
Analysis of DNA, RNA or protein (amino acid) sequences. Here sequences are compared so analyze similarities and conserved regions. Sequence analysis is usually done by specialized softeware.
× 18
Often circular segments of DNA that can replicate outside of the chromosomes. Generally found in bacteria.
× 18
The study of evolutionary mechanisms in operation at the molecular scale, primarily DNA, RNA, and proteins.
× 17
Cells which have not fully differentiated yet, i.e. with the potential to develop into other kinds of cells through asymmetric cell division.
× 17
Educated guesses about the structure and function of things that do not currently exist. Many 'what if' and 'why not' questions fit this category. Questions should be posed so that they can be answere…
× 17
The study of how biological life arises from inorganic matter through natural processes, and the method by which life on Earth arose.
× 17
Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation.
× 17
Questions pertaining to organized collections of biological data.
× 17
a single-stranded RNA virus which reproduces in human CD4-positive cells, which are primarily T-helper lymphocytes and macrophages. HIV is the causative patho…

Questions relating to the study of fish.
× 17
The timing of key events in an organism's lifetime, including development, reproduction and death.
× 17
The study of the distribution, incidence, and potential control of a disease.
× 17
The application of dynamic systems and game theory to evolving populations in biology, economics, and social sciences. It is particularly well suited for studying social dilemmas like the evolution of…
× 17
The processes by which gene products (largely RNA and proteins) are increased or decreased.
× 16
A state in which an organism or a cellular system, as defined by its full set of functionality, ceases to exist (i.e., most of the functions are irreversibly lost).
× 16
The processes by which environmental information is encoded, stored, and retrieved.
× 16 × 16
a molecular target for a chemical signal such as a neurotransmitter, hormone, or drug. Binding of the signal to the receptor initiates or modulates behaviour in the receiving cell.
× 16 × 15
Copying the genome for the purpose of reproduction.
× 15
A collection of tissues which work together to accomplish a function. The organisational unit above tissues and below systems.
× 15
Communal living, cooperation in care of young, and/or division of labor within animal species.
