The organelle in eukaryotes where the main stages of respiration occur.
Small molecules involved in the propagation of a nerve signal across the synapses.
A virus is a small infectious agent that can replicate only inside the living cells of an organism. Virology is the study of viruses.
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 software.
The entirety of an organism's hereditary information.
The physiological process of breaking down food into its constituent parts to provide nutrition for the body.
Tag for questions related to the process of cells receiving a stimulus from its environment, or from itself (autocrine signaling), and responding as a result of the stimulus.
Sensation is dealing with the processing of the senses, including the traditional senses vision, hearing, taste, smell and touch, but also sense experiences such as vestibular and pain. It typically i…
The process in nature or in the lab by which a new organism is created that is genetically identical to its predecessor.
The biosynthetic process by which copies of a DNA molecule are made.
Messenger RNA is 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.
An infection is caused by the invasion of by pathogenic organisms (bacteria, viruses or worms) into a host. These pathogenic organisms live and multiply in its host and cause diseases by this.
The study of the molecular structure of biological macromolecules and how that structure relates to their function.
Often circular segments of DNA that can replicate outside of the chromosomes. Generally found in bacteria.
Synthetic biology is an approach to engineer biology. Core to the discipline is genetic engineering, which is made more akin to engineering by adding the levels of standardization, automation, and abs…
Determining the sequence of RNA. This technique is used for discovery and quantification of mRNAs and ncRNAs.
The process of biological aging or the state of an organism being biologically old.
Division of a diploid cell to produce four haploid cells for the purposes of reproduction.
Translation is 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.
In reference to a biological system over time, growth refers to the increase in physical size/mass as well as the progression through its life cycle.

Perception is the process of attaining awareness or understanding of the environment by organizing and interpreting sensory information coming from body receptors and sensory organs into CNS.
A process defining organisms that grow and adapt to stimuli while maintaining a state of organization and energy production and being capable of reproduction.
Cells which have not fully differentiated yet, i.e. with the potential to develop into other kinds of cells through asymmetric cell division.
Mechanisms for inheriting phenotype outside of the genomic DNA sequence.
