The DNA molecule is often referred to as “The Blueprint of life”. Discuss. [SEP‚ 1999] Synopsis DNA structure Why is DNA called “blueprint” Features of the genetic code ------------------------------------------------------------------------------------- Deoxyribonucleic acid (DNA) is a vital component of both eukaryotic and prokaryotic cells. A blueprint is a detailed drawing or map which identifies and directs the construction and development of a building or an object. DNA is the hereditary

microfuge tube. Place this tube directly into liquid N2 to freeze plant tissue. 2) Remove tubes from the liquid N2 and quickly grind the plant tissue with a pestle. Add 300 L of Methanol 1%HCl and continue to grind the plant tissue. Allow extraction to occur overnight in a dark refrigerator. 3) Add 200 L Milli-Q H20 to each tube. Next‚ go to the fume hood and add 500 L of chloroform to each tube. Spin the tubes in a centrifuge set at the highest rpm for 2-5 minutes. 4) Return to

CREATE Rosalind Franklin was a chemist who made the first DNA structure in 1953. A DNA model is a model of someone’s DNA. DNA stands for Deoxyribonucleic Acid.A DNA strand is used to figure out a person’s physical and mental information. There are two forms of DNA an “A” form and a “B” form. (Franklin 2015) Franklin found this out by putting a DNA fiber under a x-ray machine Franklin refined herself. Franklin and Maurice Wilkins used Franklin’s x-ray photo called photograph 51 and Wilkins published

DNA‚ as we all know‚ is esteemed with the title of ‘Master Molecule ’. The three letters of DNA denotes of deoxyribonucleic acid .Now the thing that we ponder on is why DNA is so important to us. Why are the researchers & scientist persistently working on DNA? Why it is so important to know the tiniest details of DNA structure and function.?The simplest answer for “Why Is DNA Important?” is that DNA is the prerequisite for life’s inception. Firstly‚ it transfers hereditary information from

DNA Analysis The importance of DNA analysis has made an impact the forensic world by proving the innocence or guilt of a person. DNA analysis is the most effective method in the Forensic Investigation field‚ it carries more evidentiary value than other forensic evidence‚ it has become a primary source for cases that have not been solved and the advancements in technology will continue to scientifically eliminate wrongful convictions. Although many feel that there are discrepancies in DNA analysis

Technological developments such as DNA profiling and how investigations are conducted has significantly improved humankinds ability to investigate and solve crimes through everyday science. The use of DNA evidence in criminal investigations has helped law enforcement identify criminals and solve difficult crimes. DNA can also be used to clear the accused and free people who are wrongly accused or convicted of crimes. DNA was first described by scientists Francis Crick and James

area of DNA‚ deoxyribonucleic acid‚ helping on scientific research and most importantly as a tool for solving crimes. Before the usage of DNA‚ people only had shreds of evidence on the crime which could be detected by the naked eye. However‚ with the development of DNA detection technology‚ the police can identify or get some indication about the malefactor by collecting pieces of evidence that were impotent before; for example‚ hair‚ fingerprints and even blood (Travis‚ 1998). However‚ DNA testing
