A new research and training facility at Imperial that will construct DNA at industrial levels has been announced today by the Universities Minister. Designing‚ constructing and testing DNA is a crucial element of synthetic biology‚ an area of science which combines biology and engineering to create new biologically based devices that will help solve a range of different global challenges. These devices are made from harmless cells‚ such as yeast cells. Manmade yeast genes could then be used to

Biology: Research Task and Oral PresentationResearch Task:1.Describe some mechanisms found in Australian fauna to ensure:•Fertilisation•Survival of the embryo and of the young after birthFertilisation is the fusion of haploid sex cells in the action of sexual reproduction. It is often a difficult process as:• careful timing is required: both female and male gametes need to be produced and released at the same time• arrangements need to be made to bring the gametes together• A watery medium is always

diffusion of water molecules across a selectively permeable membrane involves a special form of diffusion called osmosis. When the external and internal solute concentration are equal‚ there is no movement of water will be observed. This is described as isotonic. Osmosis does not occur in an isotonic solution‚ because the concentrations are equal on both sides of the membrane and there is no net movement of molecules from one side of the membrane to the other (Payne‚ 2007). A hypotonic solution is a

sciences in high school‚ my interest in science has deeply increased; recently I was under pressure to choose a course of study at the undergraduate level‚ but I knew I wanted to do something in the scientific field‚ particularly along the lines of biology and chemistry. While researching various courses‚ I came across genetics‚ which was of great interest to me‚ finding out that the course included aspects such as cell mutation‚ the studying of chromosomes‚ and the behavior of micro-organisms.

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put
