DNA methylation

aquaticus has been a useful organism in the field of Biotechnology, as its enzyme Taq polymerase is harvested for use in polymerase chain reactions (PCR)- to amplify short segments of DNA. One of the advantages for this DNA polymerase was that it could be isolated in a purer form and free of other enzyme contaminants. T. aquaticus form of the enzyme is well suited for the repetitive heating involved in PCR and will not denature. Taq polymerase's resistance…

1. Is autism caused by vaccination? Despite the wide spread belief, Autism is not caused by vaccination, there is no trustworthy evidence that the vaccines today cause Autism. The person who originally came to this assumption was proven to be fraudulent, which basically means he was a sham, this lie he created caused him to lose his authenticity and medical license. However, even though the claim brought to the public was fake, people still have their doubts, simply because someone introduced…

A defined nucleus is one where there genetic material is bounded by a barrier within the cell. In a prokaryote the region where most of the DNA of the cell is located is called the nucleoid which is free floating within the cell. While in a eukaryote most of the DNA of the cell is located in the chromatin which surrounds the nucleolus. The nucleolus is where ribosomes are assembled. The nucleolus and chromatin and then enclosed by the nuclear membrane…

The brave new world book was written by Aldous Huxley where he created and illustrated a fictional world that everyone is cloned, classified since birth into Alpha, Beta, Gamma, Delta, Epsilon. In Huxely's argument, In that society, humans are genetically reproduced and are conditioned to serve a ruling order. In this society disease, poverty, and suffering has disappeared from Earth. The different types of people of the book have similarities and differences compared to our present society.…

Both cilia and flagella found protruding from the cell body on the surface of eukaryotic cells are made of many microtubular bundles. Cilia are hair-like structures that protrude from the cells surface in eukaryotic cells they are covered by a plasma membrane. They are formed from a stable bundle of microtubules; these grow from an area in the cytoplasm called the basal body. Microtubules are made of a protein called tubulin, alpha has a slightly negative charge and beta has a slightly positive…

Many living organisms rely on the environment for essential resources, including water, food, and shelter. However, they not only need the help of the environment but also other species that live within the biosphere. This lab aided in demonstrating how the affect of one organism has on another, and whether or not it benefits either organisms or one organism. In order to progress with the experiment we first have to identify our variables that will be used during the experiment. The independent…

Cutting precisely on the lines, making sure I didn’t stray and accidently cut out part of an article, I carefully extracted the Sudoku puzzle from the daily newspaper before my father came to the breakfast table to read it. Then, working as fast as I could, I began deciphering the puzzle, eliminating numbers I knew didn’t belong in a certain box and writing, in tiny print, all the numbers that could potentially fit. Gradually, as the pieces came together, the completed puzzle unfolded. I glanced…

Lethal alleles Lethal alleles cause death of the organism that transports them, normally they are the result of genetic mutations in the genes which are vital to growth and development. Lethal alleles can be recessive, dominant or conditional depending on the genes involved. Examples of the mutations caused by the lethal alleles are cystic fibrosis and sickle cell anaemia. Incomplete dominance Incomplete dominance is a part of inheritance, when one allele for a precise trait isn’t completely…

Rett Syndrome is a postnatal neurological disorder that almost exclusively affects girls. It is a rare disease and can have many side effects in each stage of life. EEG has been shown to be critical in helping diagnose Rett Syndrome. Although it has no cure, with proper treatment of the symptoms the disease can be managed. Rett Syndrome was first described in 1966 in a journal by Austrian physician, Dr. Andreas Rett. However, the disorder was not fully recognized until 1983 when it was…

Fungal Keratitis Overview Keratitis is a generalized term used for the ‘Inflammation of Cornea'. Fungal Infection cause the inflammation of cornea for example Fusarium (one type of fungi) when causes Keratitis it is called 'Fusarium Keratitis'. Keratitis may be Superficial or deep, superficial Keratitis affects the superficial layers of cornea and after treatment leaves no scar while the deep Fungal Keratitis may or may not leave a scar after healing which may or may not affect vision of the…
