Basic cytoskeleton proteins
By: Jennifer Allsbrook
The Cell Cytoskeleton: Deposing the Blob Myth Cells, the most basic units of life we each studied in school, are complex machines dumbed-down to be membrane-enclosed, fluid-filled blobs. The beautiful compartmentalization of the eukaryotic cell is unseen by the average Joe. Hundreds of metabolic reactions...
What are enzymes and what are they used for?
By: Jennifer Allsbrook
Metabolism, the totality of all the chemical reactions that occur in an organism, is a complex tapestry of chemical change woven together by the action of enzymes. In organisms, chemical reactions require an initial input of energy called the energy of activation. Some reactions can...
Explanation of protein synthesis
By: Jennifer Allsbrook
In the early years of the twentieth century, researchers began to realize a connection between genes and proteins. This groundbreaking realization of George Beadle and Edward Tatum (Campbell, 2005) came years before the knowledge needed to understand the nuts and bolts of the process known...
Structure and function of the cell membrane
By: Heather Lyon
Cells, whether it is animal, plant or bacteria, have many different parts or organelles. Each organelle has a different and important function within the cell. If any of the parts fail then the cell ceases to function and it begins to die.One of the...
Meiosis explained
By: Jennifer Allsbrook
Meiosis, also known as reduction division, is the process of cell division by which diploid (2n) organisms create the haploid (n) gametes needed for sexual reproduction. Diploid organisms have two full sets of chromosomes, which exist in pairs known as homologous pairs. Each homologous pair...
Ribosomes: an explanation
By: Debbie Luyo
Ribosomes are tiny cellular workshops where proteins, also known as polypeptides, are assembled, in the process known as translation. Messenger RNA, or mRNA, transcribed from DNA, is the template for synthesis of proteins essential for biological function. During translation amino acids are joined together to...
Explanations of the cytoskeleton of living cells
By: Tami Port MS
The cytoskeleton is a network of protein fibers that acts as a kind of scaffolding, giving shape and protection to both prokaryotic and eukaryotic biological cells. However this minute network does much more than keep the cell in its proper shape. * Cytoskeleton in Motion...
Advantages and disadvantages of genetic engineering
By: Izra Jute
The application of genetic engineering on human beings relates to the controlled alteration of all the genes in the human chromosomal. Deoxyribonucleic acid, otherwise known as DNA, is responsible for the genetic characteristics for every living organism. It can influence the individual's physical appearance, actions...
Do you think genetic altering is right or wrong?
By: Paula Rapp
Gene Deep Beauty:Breast augmentation, liposuction, face-lifts and nose jobs have become so commonplace that the procedures have long ceased to create any questions or controversy. The old familiar adage claims, "Beauty is in the eye of the beholder," yet the perception of beauty is...
Do you think genetic altering is right or wrong?
By: Steven Cuthill
Cloning of embryos brought us Dolly the Sheep and other animals including cows, pigs and cats have been cloned. That is one side of the story in the development of scientific techniques to advance understanding in embryos and cloning. Legislation in the UK has changed...
