Gene Cloning Methodology of DNA What is DNA? DNA was discovered by the Swiss biochemist‚ Johann Friedrich Miescher‚ in 1869‚ while he was working in Tubingen‚ Germany. He found that the DNA molecule is large; acidic in nature and rich in phosphorus‚ but only in the 1930s was the real and complex structure of DNA fully studied. DNA (deoxyribonucleic acid) is the genetic material in all prokaryotes and eukaryotes‚ i.e. it is the material responsible for the transfer of hereditary traits from

2011 What is Nano DNA Sequencing? DNA strand is threaded through a nano-pore and its sequence is identified from fluctuations in ionic current. (9) Trick is to figure out how to slow the strands movement through the opening so the base pairs A‚T‚C ‚& G can be read. (1) Example: graduate Brown student attached DNA strand to a bead using an electric field to drive the DNA to the pore. The DNA was too large for the pore‚ so‚ the bead was stuck in the hole with the attached DNA strand suspended

Many people believe that DNA profiling is not a credible source. Although 99.9 percent of human DNA is the same in everyone‚ the remaining 0.1 percent which consists of about 3 million base pairs of amino acids is unique to that individual (Ballaro and Walter). Without the help of scientists and their technology many criminals would get away with their crimes. Deoxyribonucleic acid‚ or DNA‚ is a component of every cell in the human body. DNA can be found in any organic source for example saliva

DNA Profiling for Crime Investigation Rabia Awan Preston University Islamabad‚ Pakistan rabiawan079@gmail.com Abstract— DNA profiling also called as DNA typing or Gene fingerprinting has been used as a powerful process for identification of humans. Many countries around the world where forensic databases have created to store DNA patterns(DNA profiles) of crime scenes in order to put the actual criminals behind the bars and free the innocent who have been kept in jails for years without any

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

Identification of A Mixed Culture Unknown An experiment such as this one serves the purpose of allowing us‚ the students‚ to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the
