The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin’s‚ Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels‚ less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged.This is what causes the problems of sickle

Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some

expression is the ability of a gene to produce a biologically active protein. This process is regulated by the cells of an organism‚ it is very important to the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane‚ which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity of RNA polymerase

Introduction Using microscopes allows humans to see things they’ve otherwise would have never seen before‚ like cells. A cell is the basic unit of life. All living things are made of cells. All cells come from preexisting cells through a process called cellular division. There are two types of cells‚ eukaryotes and prokaryotes. Prokaryotes are very simple and small. They are unicellular and have no membrane bound organelles. Their DNA is found directly in the cytoplasm since they have no nucleus

Review Chapter 4 BB Notes Cells Under the Microscope Cells are microscopic in size. Although a light microscope allows you to see cells‚ it cannot make out the detail that an electron microscope can. The overall size of a cell is regulated by the surface-area-to-volume ratio. 4.2 The Plasma Membrane The plasma membrane of both prokaryotes and eukaryotes is a phospholipid bilayer. The phospholipid bilayer regulates the passage of molecules and ions into and out of the cell. The fluid-mosaic model

CELL PHONE CLONING Abstract You might have read news of the cloning of sheep or cattle with amused interest. But how would you feel if somebody `cloned’ your mobile phone? Technology is finally rearing up its dark side. Along with the proliferation of technological innovations‚ this era also marks the birth of the new-age IT criminals in a big way‚ with the latest technology fraud being cell phone cloning. Cell phone cloning is a technique wherein security data from one cell phone

Abstract Sickle-cell disease is a genetic disorder that results from the abnormal structure of red blood cells. The peculiar shape of the red blood cell prevents the normal absorption of oxygen. This disease results from the abnormal production of hemoglobin S (HbS). Therefore‚ a mutation in this gene causes a lower supply of oxygen to the cells‚ which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit
