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.
A rapid change in the membrane potential of excitable cells such as neurons and muscles; this usually involves a steep rise (depolarization) followed by a steep fall in membrane potential (repolariza…
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…
Mechanisms for inheriting phenotype outside of the genomic DNA sequence.
A process defining organisms that grow and adapt to stimuli while maintaining a state of organization and energy production and being capable of reproduction.
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).
