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

Today science technologies are beyond incredible and can enhance our level of understanding about the past‚ present and future Earth. It allows us to see beyond our history and where and how we first came to be‚ tracking the little but significant details which allows science to trace our own ancestral journey out of Africa. The National Geographic’s Genographic Project aims to map historical human migration patterns by collecting and analysing DNA samples from hundreds of thousands of people from

GENETIC TESTING Genes‚ the chemical messages of heredity‚ represent a blueprint of our possibilities and limitations. The legacy of generations of ancestors‚ our genes carry the key to our similarities and our uniqueness. When genes are working properly‚ our bodies develop and function smoothly. But should a single gene or even a tiny segment of a single gene go askew‚ the consequences can lead to deformities and disease‚ even death. In the past 20 years‚ amazing new techniques have allowed

becoming keener to the field of engineering. Genetic engineering that is. When one thinks of “genetic engineering‚” the first thought is probably a perfect child‚ or paradoxically some inconceivable creature‚ forged under the microscope in a scientific laboratory. Though both of these are genetic engineering‚ many people do not consider other things‚ such as genetic engineering of agriculture and medicine‚ both of which are extremely useful. Through the genetic altering of plants and crops‚ scientists

Keywords: genetic‚ engineering‚ crops‚ pros‚ cons‚ world‚ hunger‚ technology‚ altered‚ tolerated‚ drought Genetic engineering the deliberate modification of the characteristics of an organism by manipulating its genetic material (Bensel‚ 2011).

allows a genetic breakthrough to be acknowledged by humanity in a matter of mere minutes. However‚ even with extreme bursts of technology‚ there are many mysteries that this world harbors which scientists have been trying to unravel for many decades. Many of these mysteries have much to do with the complexity of a muscle that is located underneath the human skull in which is called the brain. Technological advancement has allowed scientists to understand the intricacies of genetics. Genetics are linked

Genetic disorders are a topic in biology that can not be avoided. The fact is that genetic disorders can happen in humans‚ plants or animal. No one and nothing is safe from a genetic disorder. A genetic disorder can appear in the first years off life‚ or can appear much later in life when least expected. A basic principal of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns. There are many reasons for genetic disorders. To start

By having different genetic combinations‚ those of a population reveal different traits which may or may not be to their benefit‚ in respects to their social and environmental interactions or surroundings.
