Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

Restriction Fragment Length Polymorphism (RFLP) Restriction Fragment Length Polymorphism (RFLP) Definition Definition In molecular biology‚ restriction fragment length polymorphism‚ or RFLP is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules that come from differing locations of restriction enzyme sites‚ and to a related laboratory technique by which these segments can be illustrated. In RFLP analysis

organisms) is used when we refer to crop plants using different molecular biology techniques or methods to change their properties‚ such as to enhance their resistance to herbicides‚ improve nutritional content‚ and other properties. This seems great‚ but why there are people who disapprove the development and consumption of GM foods? Modifying plant genetics can have many benefits‚ because of the use of precise and accurate molecular techniques‚ the main difference between traditional breeding techniques

Biochemistry is a very interesting subject to study and eventually work in. From studying microorganisms to creating medicine to prevent alien viruses from infecting people‚ it has always been a fascinating subject to me. I became interested in this career because I was always interested in the science field. Ever since I was young‚ I always liked to experiment with different things. I found out about biochemistry by my chemistry tutor. In the first semester‚ I struggled with chemistry so I called

genetic traits‚ and non-coding DNA which does not have this function(Otto & Towle‚ 1969). Many organisms have a complete set of this DNA in almost every cell. A routine procedure to collect genomic DNA for subsequent molecular or forensic analysis is often carried out by molecular biologists. This procedure is known as DNA extraction/isolation. DNA extraction is of outmost importance in the scientific world as it allows scientists to observe‚ manipulate and classify the DNA. From studying extracted

Since I am a biology major‚ I thought this would be the perfect opportunity to compare two prospective courses I could be taking next semester. One of these classes‚ specifically‚ is Biology 121. Biology 121 is the first half of a two-semester introduction over the major components of Biology. The course discusses molecular and cellular biology‚ genetics‚ and evolution. The

GMO’s for Food? I chose an article on GMO’s more commonly known as genetically modified organism commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. The article was called Harmful or Helpful by Deborah B. Whitman; she has a B.S. in biology and an M.S. in biotechnology. Whitman attended a meeting in 1999 in Washington D.C. this meeting was to solicit public opinions on what actions should be taken for a new regulatory procedure
