Genetic diversity

Introduction DNA makes up the genetic material for all organisms. However, not all organisms have distinct molecules working with DNA that come together to make up chromatin. Chromatin is only found in eukaryotic cells, the cellular makeup of multicellular organisms. The structure of chromatin is composed of DNA and histones, together making up nucleosomes, and other non-histone proteins that bind to the DNA. The backbone of DNA is negatively charged and histones have a positive charge…

-In a SCNT, the nucleus of an egg cell is removed and it becomes an enucleated egg cell. -The nucleus is removed because the nucleus contains the majority of the genetic information (DNA). -DNA has a double helix structure and it is made from many nucleotides -Nucleotides are made from a nitrogen base (Adenine, Guanine, Cytosine, or Thymine), a phosphate group, and a deoxyribose. -The DNA is stored in the nucleus as chromatin, but during cell division the DNA stored as chromatin condense into…

Abstract Tafazzin, encoded by the TAZ gene, is a mitochondrial membrane-associated protein that remodels cardiolipin (CL), an important mitochondrial phospholipid. CL is essential for proper mitochondrial structure and function, ensuring proper functioning of energy production and apoptosis. TAZ mutations are associated with the X-linked metabolic disorder, Barth syndrome (BTHS). BTHS is a lipid metabolic disorder that affects mitochondria that is often fatal in infancy and early childhood, due…

Each year about four million babies are born around the world. Out of four million only three percent will be born with a genetic disorder and around one percent of the babies will be born with chromosomal abnormality. The reactions to these disorders vary from stares to happiness, resulting in the child feeling different or abnormal but it should not be a thing to frown upon. Ectodermal dysplasia is a group of syndromes that involve defects in the skin,hair, and nails. There are about more…

world, or why it is a disaster waiting to happen. The subject matter has created much controversy about everything from its ethical validity to its unnatural process. Cloning, in general, is the process of creating an exact copy of something. In genetics, cloning refers to the process of making an identical copy of the DNA of an organism. Many argue that cloning has benefits such as being able to cure diseases and prolong life, however, everything has a good and a bad side. I, for one, am…

The four forces of evolution is natural selection, genetic drift, gene flow, and mutation. To start of, natural selection is when organism adapt to their environment and the animals that can't eventually die off. For instance their were other species of cheetahs but the ones that are alive now were selected from natural selection because they were the strongest and the ones that could reproduce more. Genetic drift is a change in a species that might or might not exists in the future. For…

Highlands Ranch, CO, June 22, 2012 Dr. Chad Prusmack, through his nutraceutical company PruTectRx, has been authorized by T.A. Sciences to prescribe the telomerase activator, TA-65. Popularized by Suzanne Somers in her book, Bombshell: Explosive Medical Secrets that Will Redefine Aging, TA-65 has been shown to lengthen telomeres in DNA strands, which can help slow aging, hinder the development of cancer and decrease genomic instability. TA-65 is only available through authorized,…

compartments. Unlike eukaryotes, the prokaryotes concentrated their genetic materials in a small portion of cell’s cytoplasm known as nucleoid. Almost entire prokaryotic genome is contained in a single circular DNA strand that is supercoiled. Some additional genes are located on an independent small, circular or linear plasmids which coding for extra properties likes antibiotic resistance (Brown, 2002). Typically, prokaryotes lack of genetic organization compared to eukaryotes. So, they own a…

A small percent of people with Alzheimer’s carry the gene of ApoE which increases the risk of Alzheimer's. The gene is so rare because it’s part of a genetic disease which and if your family has it you are highly prone to getting the disease. Age is the primary risk factor for Alzheimer's disease. The number of cases of Alzheimer's disease doubles every couple of years in people over 65. At around 85,…

“A Powerful New Way to Edit DNA” tells the beginning of gene editing. It all starts with Japanese scientist noticing unusual repeated DNA sequences. This later helped scientist to realize that DNA could be edited. Within this article it talks about different discoveries about genome editing and also has an educational image of Crispr editing. This article answers the questions of what is gene editing, what it might treat and the biggest hurdle. Also the ethnic controversy, if it is legal and…
