Cancer is the uncontrolled growth of abnormal cells in the body. When cells in part of the body become overactive‚ cancer begins. Many kinds of cancer start because of the out of control growth of abnormal cells. How can you prevent cancer? Research shows that there are ways to prevent cancer. Avoiding smoking cigarettes and exposure to smoke will decrease the chances of getting lung cancer. Fruits‚ vegetables and a well balanced diet are important to keep healthy and will help repair damaged

Four main solutions for this are micelles‚ liposomes‚ monolayer and bilayer sheet. Micelles uses the least amount of phospholipids as it forms a small single layer spherical ball with the hydrophobic tails surrounded by the hydrophilic head keeping the water out. Liposomes are similar to micelles but yet are larger and duel layered (bilayer) as well as the outer layer it has another inner layer of phospholipids from another aqueous environment that the liposome has formed round. The Monolayers can only

INSERT TITLE AND WORD COUNT In the last century‚ there have been a number of discoveries regarding the treatment of human disease and genetic conditions. The current on-going research is in the field of gene therapy‚ an experimental technique that uses genes to treat and replace the defective genes of an affected person. Instead of treating disease symptoms‚ this has the potential to correct the underlying cause (1). Besides its high costs and ethical concerns (therapy involving germ line treatment)

for Cystic Fibrosis Cystic Fibrosis‚ also called CF‚ is the most common life threatening disorder in the US. It is an inherited disease of the secretory glands (National Blood‚ Heart and Lung Institute‚ 2013). Affecting about 30‚000 people‚ it is an autosomal recessive disorder due to mutations in the CF transmembrane conductance regulator (CFTR) gene (National Blood‚ Heart and Lung Institute‚ 2013). Usually diagnosed at a young age‚ CF causes the mucus‚ sweat and digestive fluids to become thick

“infects” the target area with the healthy gene and so the cells can produce functioning proteins again. The genes can also be directly introduced to the target cells; this can only used in some tissues though. Also an artificial sphere‚ called Liposome‚ can be used which carries the DNA and is capable of passing the DNA through the target cell’s membrane. Another way is to chemically link the DNA to a molecule that will bind to specific cell receptors. Then the DNA will be passed into the target

Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA‚ as well as cell membrane encompassing the cell to control the substances moving in and out of the cell. They both contain enzymes from liposome for breaking down larger molecules. Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum and have vacuoles where food‚ water‚ and nutrients are stored as well as provide stability for a plant.

structural components of cell membranes‚ and as important signaling molecules.[4][5] Lipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles‚ liposomes‚ or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks":ketoacyl and isoprene groups.[4] Using this approach‚ lipids may be divided into eight categories: fatty
