Explanation of protein synthesis
By: Nayab Sh
Protein synthesis, a way of gene expression in which gene produces a product, usually a protein. It involves two stages; Transcription and Translation.Transcription is a process of RNA synthesis in which RNA molecules are synthesized on DNA template. As in eukaryotes DNA is restricted...
Biology: The Golgi apparatus
By: Megan Worley
Within each cell, both plant and animal, there are essential parts that have a variety of functions. One of these organelles is the Golgi apparatus which is important for dealing with proteins. It is often termed the post office of the cell because it is...
Mitochondria defined
By: Nayab Sh
Mitochondria are sausage-shaped, double membraned cytoplasmic bodies usually called "Power House Of Cell". These are responsible for ATP synthesis through cellular respiration. Mitochondria are present in almost all eukaryotic cell with the exception of protist Chaos (Pelomyxa) carolinensis.They show constant motion within the cell...
The cell nucleus
By: Megan Worley
The cell's nucleus is usually the largest organelle in a cell. It is substantially larger in animals cells that in prokaryotic cells. The nucleus has three major roles within the cell. The nucleus is the site for DNA duplication to support cell reproduction as well...

The Kingdom Monera is a catch-all top-level classification for the prokaryotic organisms that was in common usage during the mid to late twentieth century. The Monera consists of those organisms that have their genetic material loose in the cell rather than packed into a cell...
The cell nucleus
By: Nayab Sh
Cell nucleus is spherical or semi spherical body present usually in the center of eukaryotic cells. In prokaryotic cell, nuclear material is dispersed throughout the cytoplasm without a definite membrane. Nucleus is often called 'Brain Of The Cell' as it contains cell's hereditary material DNA...
Introduction to mitosis
By: Aleksander Leskiw
Most eukaryotic cells divide and multiply through one of two cellular processes: mitosis or meiosis. The basic premise of both processes is fairly similar: replicated DNA is split and the cell divides to form daughter cells. However, mitosis differs from meiosis in that it produces...

Genetic engineering is one the next great scientific advances that will lead humanity into a new age (if ever it is deemed ethical), and so, unsurprisingly, it is a subject faced with controversy and argument. This author is in favour of genetic engineering.Previous scientific...
Introduction to mitosis
By: are-peace
DEFINITIONAll living organisms in this world are made up of cells. Cell (cellulae) is the basic unit of life. All cells undergoes numerous processes including cell division. Cell division can be divided into two types: mitosis and meiosis. All types of cells except gametes undergo...
The basics of gel electrophoresis
By: Alex Powell
Electrophoresis is the movement of charged particles in an electrical field, first characterised in solutions by F.F. Reuss. In short, the higher the voltage, the lower the viscosity of the medium; the smaller the charged particle and the greater the charge on that particle...
