Bacterial cell divisionsPG synthesisMost bacteria assemble a ring-like macromolecular machinery scaffolded by the essential cytoskeletal protein FtsZ for cell division. Studies have broadly explored how FtsZ could polymerize at the correct place and time. Recently, the FtsZ-ring was found to exhibit ...
Embryonic Stem Cells HowStuffWorks / Lee Dempsey Once an egg cell is fertilized by a sperm, it will divide and become an embryo. In the embryo, there are stem cells that are capable of becoming all of the various cell types of the human body. For research, scientists get embryos in ...
This is why, when a child is found to have an abnormality, chromosome studies are often performed on the parents. National Human Genome Research Institute In the human genome, there are 50,000 to 100,000 genes. As DNA polymerase copies the DNA sequence, some mistakes occur. For example,...

The ribs divide the parachute into a set of individual cells. Air enters, or rams, into the front of the canopy to inflate the cells and give the parachute an airfoil shape. This shape makes the parachute act like a wing (see How Airplanes Work for a description of wings). Instead of...
Once an eggcellis fertilized by a sperm, it will divide and become an embryo. In the embryo, there are stem cells that are capable of becoming all of the various cell types of the human body. For research, scientists get embryos in two ways. Many couples conceive by the process ofin ...
