Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
Artificial cells used for drug delivery differ from other artificial cells since their contents are intended to diffuse out of the membrane, or be engulfed and digested by a host target cell. Often used are submicron, lipid membrane artificial cells that may be referred to as nanocapsules, nanoparticles, polymersomes, or other variations of the ...
2 H 2 O → 2 H 2 + O 2 This scheme is the simplest form of artificial photosynthesis conceptually, but has not been demonstrated in any practicable way. Light-driven carbon dioxide reduction, the conversion water, carbon dioxide into carbon monoxide or organic compounds and oxygen. In the conceptually simplest manifestation, this process gives ...
One example of this improved protection with plasmids is use of the bacteriophage lambda gam protein. [13] Gam is an inhibitor of RecBCD, an exonuclease found in Escherichia coli (E. coli). [14] With the use of gam, CFPS yields with LETs were greatly increased, and were comparable to CFPS yields with plasmids. [15]
Bioprospecting (also known as biodiversity prospecting) is the exploration of natural sources for small molecules, macromolecules and biochemical and genetic information that could be developed into commercially valuable products for the agricultural, [2] [3] aquaculture, [4] [5] bioremediation, [4] [6] cosmetics, [7] [8] nanotechnology, [4] [9] or pharmaceutical [2] [10] industries.
Yeast artificial chromosomes (YACs) are genetically engineered chromosomes derived from the DNA of the yeast, Saccharomyces cerevisiae, which is then ligated into a bacterial plasmid. By inserting large fragments of DNA, from 100–1000 kb, the inserted sequences can be cloned and physically mapped using a process called chromosome walking .

In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.
