The CAR-15 Heavy Assault Rifle M2 was a belt-fed conversion of the standard CAR-15, with a heavy barrel and bipod attachment. It was made in prototype form only and saw no sales. The CAR-15 Heavy Assault Rifle M2 was not related to the CMG-1, CMG-2, or CMG-3 belt fed machine guns.
The Colt Model 933 is a compact carbine based on the AR-15, M16 rifle and M4 Carbine produced by Colt starting in 1995. Due to its compact size, the short-barreled Colt 933 continues to be used by various US Special Forces and by some foreign forces, including Israeli Special Forces.
A clone is a group of identical cells that share a common ancestry, meaning they are derived from the same cell. [ 1 ] Clonality implies the state of a cell or a substance being derived from one source or the other.
Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
Mule: Idaho Gem, a john mule born 4 May 2003, was the first horse-family clone. [57] Horse: Prometea, a Haflinger female born 28 May 2003, was the first horse clone. [58] Przewalksi's Horse: An ongoing cloning program by the San Diego Zoo Wildlife Alliance and Revive & Restore attempts to reintroduce genetic diversity to this endangered species ...
The XM7, previously known as the XM5, is the U.S. Army variant of the SIG MCX Spear, a 6.8×51mm (.277 in), gas-operated, magazine-fed assault rifle [1] designed by SIG Sauer for the Next Generation Squad Weapon program in 2022 to replace the M4 carbine.
Schematic representation of the pBR322 plasmid, one of the first plasmids widely used as a cloning vector.. A cloning vector is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. [1]
Usually the ultimate aim of expression cloning is to produce large quantities of specific proteins.To this end, a bacterial expression clone may include a ribosome binding site (Shine-Dalgarno sequence) to enhance translation of the gene of interest's mRNA, a transcription termination sequence, or, in eukaryotes, specific sequences to promote the post-translational modification of the protein ...
