SHIP consists of an N-terminal SH2 domain, a catalytic domain and a C-terminal tail that contains two phosphorylation sites. There are several isoforms of SHIP and the expression of these isoforms differs among different cell types. In addition, another SHIP gene, SHIP-2, has been identified. SHIP-2 is also expressed in non-hematopoietic cells.
Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
The most advanced tissue culture science is now focused on stem cells, stem cells can be used for tissue replacement or either organs. stem cell is a primitive type of cell which has the ability to differentiate to all the 220 cell types found in human body.
Stem-loops are nucleic acid secondary structural elements which form via intramolecular base pairing in single-stranded DNA or RNA. They are also referred to as hairpins or hairpin loops. A stem-loop occurs when two regions of the same nucleic acid strand, usually complementary in nucleotide sequence, base-pair to form a double helix that ends ...
A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.
A typical STEM is a conventional transmission electron microscope equipped with additional scanning coils, detectors, and necessary circuitry, which allows it to switch between operating as a STEM, or a CTEM; however, dedicated STEMs are also manufactured.
Port: the left side of the ship, when facing forward (opposite of "starboard"). [1] Starboard: the right side of the ship, when facing forward (opposite of "port"). [1] Stern: the rear of a ship (opposite of "bow"). [1] Topside: the top portion of the outer surface of a ship on each side above the waterline. [1] Underdeck: a lower deck of a ...
