Beta galactosidase is a hydrolase enzyme and it is also known as beta gal. It causes the hydrolysis of the polysaccharides that is it uses the water to break down the sugar molecules in to simpler and smaller compounds such as simple sugars. It acts on different substrates to break it down as it is a catabolic enzyme. The important substrates are lactose, lactoslyceramides, gangliosides and many other glycoproteins but lactose is an important substrate and sometimes this enzyme has been recognized

Deoxyribonucleic acid or DNA is found in basically all organisms including humans. It is the hereditary material that basically every person has and is found in both the cell nucleus and the mitochondria. Most of a person’s DNA is nuclear DNA because it is found in the nucleus; small portions of DNA can also be found in the mitochondria, giving this type the name mtDNA or mitochondrial DNA. DNA has many properties; one of its most important is that it can copy

Running head: SIGNIFICANCE OF DNA Significance of DNA Significance of DNA Deoxyribonucleic acid (DNA) was first discovered in 1869 by Johann Friedrich Miescher, but it was not until the 1950s while studying viral replication did Alfred Hershey and Martha Chase determine DNA was Genetic material. In 1953 James Watson and Francis Crick discovered DNA was a double helix (a double helix looks like a twisted ladder). The discovery of Watson and Crick opened the door helping describe the significance

chromosomes). But in addition to the role of division, meiosis has an important role in genetic mixing (miscegenation), thanks to two mechanisms shuffling: the interchromosomal and intrachromosomal shuffling) . Thus, during meiosis, the amount of DNA within the cell varies over time. Each cell will therefore separate genetic heritage (contained in chromosomes) in two to transmit only half of their genes to daughter cells. It takes place in several stages forming a set of two cell divisions

Human Gene Splicing An aspect of the future I chose was human gene splicing. I got the idea while watching reruns of Batman Beyond with my daughter. In my future scenario, human beings would be able to directly manipulate their genomes through biotechnology, and combine them with other species of animals to alter, enhance and add abilities and traits they do not currently have. In this scenario, human beings would have greater strength and vastly superior senses through the combination of their

DNA DNA or Deoxyribonucleic acid is the very building block needed in the creation of life. It is composed of genetic instruction to map out the creation of an entire organism. DNA is well suited in the storage of biological information. Yet with all of this complex information there are certain chemicals or forms of energy that can damage or alter this special coding. In process of damaging or altering the coding of DNA the most dreaded situation of a cancerous cell can be formed. To start let’s

Introduction The profound importance for microorganisms to operate at a maximum efficiency has lead to adaptations allowing for groups of processes to be functional when resources are available, while on the contrary remaining “dormant” when not in need. This has been accomplished at the molecular level by configuring clusters of genes together on the genome into operons that elicit a processive response in the presence of a specific metabolite. The Lac operon is responsible for the cleaving of

disorders also carry a high risk of cancer, siezures, heart diseases or other health problems, so knowing about them allows families and physians to be vigiliant for such issues. If a genetic mutation is found, researchers can also test the parents’ DNA to see if the problem was inherited or if it occurred spontaneously, in which case the risk of having another child with autism is no greater in the general population. Another possible outcome: The test could find abnormalities in those 30 genes-

Utopian & Dystopian Final Project Analytical Paragraph The novel, “Technophobia”, written by Daniel Dinello, reveals scientific visions of post-human technologies that will be introduced in the near future. Such machinery will dominate the lives of all humans, affecting the way they behave and the way they see the world. Scientists are striving for an advance in emerging fields of technology in order to change the future of humankind. Human bodies will soon be perfected through genetic manipulation
