News Releases. Schizophreniaâs strongest known genetic risk deconstructed. Suspect gene may trigger runaway synaptic pruning during adolescence â NIH-funded study. Versions of a gene linked to schizophrenia may trigger runaway pruning of the teenage brainâs still-maturing communications infrastructure, NIH-funded researchers have discovered.

The cytoplasmic membrane (also called the plasma or cell membrane) in eukaryotic cells, as in prokaryotes, is a fluid phospholipid bilayer embedded with proteins and glycoproteins.2, Fig. 32A, and Fig. 31).

Eukaryotes are organisms, including humans, whose cells have a well defined membrane-bound nucleus (containing chromosomal DNA) and organelles. The division between prokaryotes and eukaryotes reflects the existence of two very different levels of cellular organization.Distinctive types of prokaryotes include extremophiles and methanogens; these are common in some extreme environments.owever, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes. This is one of many pieces of evidence that mitochondria and chloroplasts are themselves descended from free-living bacteria.
