1.0 Introduction of Investigation Investigation can be defined quite simply as a systematic fact finding and reporting process. It is derived from the Latin word vestigere‚ to “track or trace‚” and encompasses a patient‚ step-by step inquiry. Investigation is finding facts; it is akin to research conducted in the academic arena. Investigation is a multi-disciplined field of study. It encompasses law‚ the sciences‚ communications‚ and a host of other things. Investigation requires an inquisitive

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

Recombinant DNA Report Our final annotated gel image sums up the successful experiments we performed over the course of 8 weeks. The image will be referred to throughout the report: Lane 1: 10 µL of ladder. Lane 2: 20 µL of a pAMP- EcoRI/HindIII double digestion. Within the double digestion‚ one can find 8 µL of pAMP‚ 1 µL of the EcoRI enzyme‚ 1 µL of the HindIII enzyme‚ 5 µL of 10x Buffer 2.1‚ and 35 µL of water. A total volume of 50 µL was present

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar

investigated the amount of DNA extracted from strawberries. This was done by using the independent variable of alcohol to affect the dependant variable of the amount of DNA extracted. This was done to find out if primary or secondary alcohol would create more DNA precipitate than the other. For this the primary alcohols used were; methanol and ethanol‚ and the secondary alcohol was; isopropyl. Of this the secondary alcohol‚ isopropyl was discovered to be the most effect alcohol to make DNA precipitate‚ as it

DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA)‚ but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of

DNA Profiling and Ethics Reflection Journal Vanshika Khemka 14th October 2012 "33 autorad off" On 10th September 1984‚ geneticist Alec Jeffrey’s wrote these three words in his red desk diary. This marked the completion of an experiment‚ which studied how inherited illnesses pass through families. The experiment failed entirely. (McKie‚ 2009) However‚ this led to the most profound discovery: the world’s first DNA fingerprint. Now‚ the smallest swab of blood or sweat can determine

(2008) DNA packaging: Nucleosomes and chromatin. Nature Education 1(1) Each of us has enough DNA to reach from here to the sun and back‚ more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? The haploid human genome contains approximately 3 billion base pairs of DNA packaged
