Follow on Google News | My Mom and I so different....DNA...Gene all that the same even I am an older boy now......I look so much like my mom, but I'am an older boy now, it show only when I'am shaved to the skin. My mom and I are different in DNA what make things easy for everyone ot rely on the fact that we are all created different.
By: Eddie Elchahed Publisher/Editor Vital Issue: Relation between genes and body fat is a big issue. Mostly the young generation is very concerned about the same. The concern is due to the increasing problems of obesity as well as its access to media. School of thoughts: A group of scientist said that, genetics is related to growing fat in a body where as another group of research fellows disagree with the fact. Basics: If we go back to the basic facts of genetics, we can find the term," trait" which means character of an individual. By the study of genes we came to know the relation between parents and the children. The inherit quality of the parents can be found in children. Since the complexion, hair color, habits etc depends on genes, we cannot ignore the reason of fats deposition due to genes. Above all we cannot claim that body fats are due to the effect of genes. At the same time we cannot deny the fact. There are yet other facts such as physical condition, which can lead to excess fats in body. The researchers make use of rats when they need to perform a specific act. They got a desired result by experimenting with rodents in laboratory. The experiment with the rat showed the growing of fat in its adulthood. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder. An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell. Fat appears to associate with some distinctive chemical changes in the DNA – a finding that may help explain why obesity can increase the risk for chronic problems such as cardiovascular disease and diabetes, researchers report. Losing fat is very difficult; we know that. We also know it causes many diseases so we want to identify and target pathways to reduce those diseases," Wang said. Fat used to be viewed as essentially padding and a ready energy source but scientists are learning it's more like a factory that makes chemicals and compounds such as hormones and proteins. Studies comparing two groups of obese versus lean teens found higher levels of chemical change, or methylation, in a portion of the UBASH3A gene and lower levels in part of the TRIM3 gene. # # # Publisher/editor/ End
