Epigenome controls the genetics of the body by determining how cells differ from one another. The cells in our body all have the same genes‚ but it’s the epigenome that differentiate the cells to become skin cells‚ nose cells‚ liver cells‚ and heart cells. Skin cells are different from nose cells because the certain set of genes are turned off by the epigenome to express what that cell will become. For example in the video the fat mice with yellow coat have the agouti gene. When the mother is given

have only one X chromosome)‚ one altered copy of the gene in each cell causes the condition. In females (who have two X chromosomes)‚ a mutation would have to occur in both copies of the gene to cause the disorder. What is the role of genetic testing ? - Genetic testing for Hemophilia A&B is to check for mutations within the genes. DNA testing would be the most accurate test for identifying carriers. A blood sample from a male family member with hemophilia is checked first. Then‚ a blood sample

Biology 2A 2/23/14 Genetic engineering is making changes in the DNA code of a living organism‚ working almost the same. It has many purposes including clones‚ perfect humans and cures for genetic diseases. Gel electrophoresis is a powerful tool used for separation and analysis of macromolecules and their fragments‚ based on their size and charge. You place the DNA in the gel. DNA is a long‚ strand-like molecule where genes are written in genetic code. Extracted enzymes recognize and extract the

* Interest and research in the brain is at an all-time pace The cure for some common diseases such as Alzheimer’s‚ Parkinson’s and Multiple Sclerosis has accelerated the efforts of many scientists * Many of the names for the parts of the brain have come from Latin and Greek words * The easiest way to learn about the brain is to look at it as three divisions; the hindbrain‚ the midbrain and the forebrain * Modern imaging has allowed us to study the brain and locate where important functions

A controversial issue of the twenty-first century is the possible application of new techniques in genetic engineering to produce human clones. Up until now genetic engineering and cloning has been used to clone plants‚ unicellular organisms‚ amphibians and simple mammals. This has led to significant advances in agriculture‚ industry‚ and medicine. Newer techniques in genetic engineering have enabled scientists to clone more complex mammals and opened up the possibility of cloning humans. Although

The Blue Brain Project is an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level. The aim of the project‚ founded in May 2005 by the Brain and Mind Institute of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland‚ is to study the brain’s architectural and functional principles. The project is headed by the founding director Henry Markram and co-directed by Felix Schürmann and Sean Hill. Using a Blue Gene supercomputer running

Mammalian Brain Dissection Purpose: The purpose of dissecting the sheep brain is to learn the structure of the brain. We must learn a brains structure to help us learn its functions‚ because they are very important and part of the Central Nervous System. We must learn the Central Nervous System to learn how it communicates between different parts of the body and the body’s interactions with the environment because it is a California standard. Analysis Questions: 1.) What observable features

Learning Team A was tasked to create a 15-20 slide presentation of a major health issue prevalent in the United States. The group chose the disease diabetes. Diabetes is a disease that affects how your body uses blood glucose. The glucose in your body is important because it is an important source of energy for the cells that make up our muscles and tissues. It is the main source of fuel for our brain.

Teenage Brain: A Continuous Mystery Everyone knows and remembers their tough teenage years. For some‚ it was the best time of their life; for others‚ the memories are the opposite. What is even more challenging than being a teenager yourself‚ is living with one. It is as if it happens over night; a happy‚ fun-loving child becomes a dramatic‚ chaotic pre-teen. In PBS Frontline’s “Inside the Teenage Brain”‚ some of the mysteries involving why and how the teenage brain works are revealed. The brain in
