public‚ and the scale has experienced multiple changes since the first day. The question is‚ do IQ-test really measures person’s intelligence? According to Howard Gardner’s article “Human Intelligence Isn’t What We Think It Is”‚ humans are multi-intelligence beings. So‚ IQ-test merely cannot provide an accurate representation of an individual’s intelligence level‚ rather IQ-tests generally measure only two forms of intelligence which are linguistic and logical-mathematical intelligences. However‚ we

The Discovery of the Structure of DNA Determining the structure for DNA was one of the outstanding science achievements of the 20th century. It started in the late 1940’s‚ when scientists were aware that DNA was most likely the molecule of life‚ even though many were sceptical since it was so "simple." They also knew that DNA included different amounts of the four bases: adenine‚ thymine‚ guanine and cytosine (usually abbreviated A‚ T‚ G and C)‚ but nobody knew what the molecule might look like

DNA‚ which stands for Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. These nucleic acids consist of long chains if chemical units called nucleotides. Nucleic acids are information storage molecules that provide the directions for building proteins. Described by the DNA testing centre‚ Inc.‚ “DNA is found inside the chromosome

Scientist extracts DNA to show how it’s useful to solve a crime scene. DNA is the most things to use for solving any crime. Finding DNA is pretty easy to find it can be you’re hair‚ blood‚ or even saliva. Using all that can help investigators to find who the criminal is. Scientist compares the DNA to make sure that their looking for the right person and not to make any mistakes. Scientists extract the DNA when they use blood‚ saliva‚ and other body fluids and tissues. For example the crime investigators

DNA EXTRACTION FROM KIWI ISGR SCIENCE Aalah Yousif‚ Ella Sobek April 27‚ 2012 Background All living organisms (plants‚ animals‚ and bacteria) are made up of cells. Any cell consists of many parts but the parts that play the key roles are the nucleus‚ cell membrane‚ and cytoplasm. The nucleus is like the “brain” of the cell (that also contains DNA). The cell membrane is like a wall that guards the cell. And the cytoplasm is a jelly-like substance which contains other smaller organelles like

Using DNA in Science and Technology DNA is the blueprint for life‚ it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles‚ such as plasmids in bacteria‚ chloroplasts in plants‚ and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes‚ and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure‚ its sugar phosphate backbone‚ made up of deoxyribose and a phosphate

Djina Jan-18-15 Lab #6 - DNA Extraction lab Introduction: DNA is a double stranded macromolecule composed of nucleotide bases pairing Adenine with Thymine and Cytosine with Guanine. S ince DNA is the blueprint for life‚ every living thing contains DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect

Power of DNA Analysis In the world of medicine and disease there is one disease that is as well known as it is deadly: Cancer. Many people understand the severity of cancer and how it attacks the immune system and ultimately can kill a person. The war on cancer was started in 1971 by President Nixon and this set of four decades worth of study and has lead to a large amount of information being learned about the cancer genome. A new strategy has recently surfaced and is gaining ground‚ DNA analysis
