Creutzfeldt Jakob Disease Nucleic Acid
1,120 wordsOver the years there have been many documented cases of diseases for which there appeared to be no cause. Only within the late 20 th century has the reason for these illnesses been brought into the spotlight. The symptoms of these illnesses are usually the loss of coordination followed by dementia, but in some cases an inability to sleep develops into dementia. These symptoms are caused by damaged regions of the brain. This damage occurs in the form of normal tissue changing to a sponge-like con...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 wordsThe nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...

Sickle Cell Disease Red Blood Cells
1,334 wordsdisorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin's, Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged. This is what causes the problems of sickle cell disease. As to this day there is really no ...

Thousands Of Years Amino Acids
637 wordsThe choice of eating meat or not has been a debated issue for a continued number of years. There have long since been two sides: the proponents and opponents of meat consumption. More and more debates of its value and effect on the world have risen. Many claim it is wrong, while others think of it as a needed pleasure. Today, a greater percentage of the population eats meat. Only a few individuals seek the alternative route. Yet, there has been a steady rise in the number of vegetarians. Many ma...

In 1953, James Watson and Francis Crick made the makeup of the genetic code called deoxyribonucleic acid, or DNA, the genetic material that is in all living cells. Deoxyribonucleic acid encodes the order of amino acids that have pe...

Biology essay The finding of the Introns and the exons was one of the most significant discoveries in genetics in the past fifteen years. split genes were discovered when lack of relation between DNA sequences were seen during. DNA- mRNA hybrid ation. For all new mRNA, they must be transcribed by RNA polymerase enzymes. The transcription begins at the promoter sequence on the DNA and works down, thus the nucleotide sequence of the mRNA is complimentary to the ...

The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reduce the Caprice ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when at low levels. In both the onion juice and glucose solution the reducing sugar levels were very high, because the test came back dark oran...
