DNA Report :: Biology

Many people have heard about this undercover deoxyribonucleic acid molecule but dont know much about it (what it is, where its located, what it does, etc.) In this report it will state the basics and investigate this mysterious molecule deoxyribonucleic acid. deoxyribonucleic acid is a thin chainlike molecule found in almost every cell (Rubenstein, 2006), and is used in developing and surgical process all known living organisms (Wikipedia, 2009). DNA is a Hereditary Material in a human body, (U.S. National, 2009), genomes determine hereditary (Rubenstein, 2006). The main purpose for DNA is long-term storing of information (Wikipedia, 2009). Basically DNA is biological information exchanged from adult to child through reproduction (National humans, 2008).DNA is formed in the nucleus of a cell (National Human, 2008). Most DNA is found in the nucleus and a small bar is found in the Mitochondria. When DNA is found in the nucleus it is considered to be Nuclear DNA and when D NA is found in the Mitochondria it is considered Mitochondrial DNA (U.S. National, 2009). humankind always get 50% of DNA from your mom and 50% of DNA from your dad through reproduction although only Mitochondrial DNA is from your mom because during fertilization pelt cells only keep Mitochondria (National Human 2008). Sometimes DNA can be found in bacterial cells and in viruses (Rubenstein, 2006).DNA is made of numerous different resources found in a human body chemicals, bases, and more. Deoxyribonucleic acid is made of three basic chemical building blocks a Phosphate group, a Sugar group, and 1 of 4 nitrogen bases. DNA is made of 3 billon bases (National Human, 2008), 99% of these bases are the same in all humans (U.S. National, 2009), and the modulate and amount of the bases determines that humans unique self (Rubenstein, 2006). Bases are connected by hydrogen bonds, base pairing is very specific Adenine only with triiodothyronine and Cytosine only with Guanine (Compto ns, 2008). Each DNA that contains instructions, that makes protein, is considered a gene gene size varies from 1 thousand bases to 1 million bases (National Human, 2008). A gene carries genetic information during reproduction (Wikipedia,2009). DNA consists of thousands of chemical units called nucleotides (Rubenstein, 2006). Nucleotides are linked together by covalent bonds linking phosphate of one to plunder of the next (Comptons, 2008). Like genes the exact amount and order of Nucleotides varies, making the person only themselves (Rubenstein, 2006).
