Often circular segments of DNA that can replicate outside of the chromosomes. Generally found in bacteria.

The eukaryotic process characterized by replication of nuclear DNA and formation of a second identical nucleus. Separate from cytokinesis.
× 22
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.
× 22 × 22
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.
× 22
The processes by which gene products (largely RNA and proteins) are increased or decreased.
× 22
Questions pertaining to organized collections of biological data.

Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation.
× 21
Questions relating to the study of fish.

Questions relating to the binding of proteins to each other and other molecules.

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.

a polyphyletic group of unicellular fungi. Usually the term yeast is used synonymously with baker's yeast - Saccharomyces cerevisiae.

The concepts of mate choice and competition over eligible members of the opposite sex in animals, including humans.
× 20
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).
