cause a protein to unravel and lose its normal shape. This is called denaturation of the protein. 4. Explain the differences between DNA and RNA? The difference between RNA and DNA is that instead of the base thymine, RNA has a similar but distinct base called uracil. Except for the presence of ribose and uracil, an RNA polynucleotide chain is identical to a DNA polynucleotide chain. RNA

attempt to explore the philosophical controversies that represented by “new and emergent science”. The field of new and emergent science includes many other sub topics such as human cloning, animal cloning, nanomachines, human genome mapping, and DNA altering. I believe that a person could write many books while only scratching the surface of the philosophical debates that surround these intense issues. I believe that there are specific parts of these new sciences and technologies that a postcolonialist

or metabolize food, and which therapies our bodies do and do not respond to (Hart, 2005). The genome consists of an organism's total DNA, including its genes. DNA—the famous "double helix"—is composed of four chemicals, which are repeated many times in different sequences (Jain, 2007). (The names of the chemicals are abbreviated as A, T, C, and G. That's why DNA is sometimes referred to as a code with a four-letter alphabet) (Jain, 2007). The sequence of the chemicals dictates the type of organism

Heredity and Hormones One day I was at the mall in store a lady came up to me (total stranger) and stated “You must be Stephen Craig’s daughter, because you look just like him. Your mother did no work in creating you.” I told the lady yes I was his daughter but what amazes me was this lady I never met knew my father and stated that I look just like him. Resembling a family member physically or mentally is something that has happen in the past and will continue to happen, but it makes

Cancer is as a disease when cells divide uncontrollably, involving unregulated cell growth. Ever cell in your body contains DNA (deoxyribonucleic acid) every DNA contains information about how to grow and what kind of cell it is. When DNA gets damaged it fixes itself with creating new strands but if it’s damaged beyond repaire it dies out. Some times the damaged DNA does not die but continue to multiply and make new copies even though that its damaged and not needed anymore. This Damaged cell leads

Morphology Enterovirus is protein capsid and single stranded positive sense RNA. When stained it looks like DNA virus almost identical in size to herpes virus. Both virus have enveloped forms and displays protein membrane subunits. Diseases This virus can cause Polio. Signs and symptoms Minor symptoms are as fallows fever, fatigue, nausea, headache, and
