Building on the fluid mosaic model, a framework called the proteolipid code was proposed in order to explain membrane organization. [8] The proteolipid code relies on the concept of a zone, which is a functional region of membrane that is assembled and stabilized with both protein and lipid dependency.
[5] [17] Likewise, a loss of the Y chromosome can result in XY/X mosaic males. [18] An example of this is one of the milder forms of Klinefelter syndrome, called 46,XY/47,XXY mosaic wherein some of the patient's cells contain XY chromosomes, and some contain XXY chromosomes. The 46/47 annotation indicates that the XY cells have the normal ...
Garth L. Nicolson (born October 1, 1943) [1] is an American biochemist who made a landmark scientific model for cell membrane, known as the fluid mosaic model.He is the founder of The Institute for Molecular Medicine at California, and he serves as the president, chief scientific officer and emeritus professor of molecular pathology.
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
Another modern mosaic of note is the world's largest mosaic installation located at the Cathedral Basilica of St. Louis, located in St. Louis, Missouri. [30] A modern example of mosaic is the Museum of Natural History station of the New York City Subway (there are many such works of art scattered throughout the New York City subway system ...

The movement of phospholipids, even those located in the outer leaflet of the membrane, is regulated by the actin-based membrane skeleton meshwork.Which is surprising, because the membrane skeleton is located on the cytoplasmic surface of the plasma membrane, and cannot directly interact with the phospholipids located in the outer leaflet of the plasma membrane.
To improve the images in Wikipedia's coverage of Biology articles. To encourage promising students to write, create, learn, and contribute volunteer efforts through a service learning project. The dreaded “Research Project” is a standard hurdle for most AP Programs.
