DNA Barcoding Click on the following link and view the background on DNA barcoding: https://www.dnalc.org/resources/animations/dna-barcoding.html 1. What is a DNA barcode? DNA barcoding is a fast accurate method of identifying plants and animals‚ or products made from them. DNA barcode is DNA sequence that uniquely identifies each species of living things. Short DNA sequences are used to identify species by comparing them with the known barcodes in large databases. When you get to the section where

DNA fingerprinting is a method that compares the fragments of DNA. DNA fingerprinting was first invented to detect the presence of genetic diseases. Today‚ DNA fingerprinting is used in different ways. DNA is analyzed using a Southern Blot‚ which allows scientists to observe the base pair patterns. DNA fingerprinting can be used in a few different ways. First‚ to find out if the child belongs to a person DNA fingerprinting may be used. When a child is born‚ it inherits the VNTR’s from the father

The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome

DNA Sequencing As of last few weeks‚ the transformation lab is performed to convey and purify a given protein. However after further research scientists found out that Transformation is not only used to purify protein but also to find out contents that are stored in a given plasmid. The objective of the lab that is to be performed involves a procedure that determines the identity of an unknown gene replicated in a plasmid. To begin this procedure two to four colonies of bacteria is added to two

DNA Cloning ~ The Future of Science DNA Cloning DNA cloning is the process where an exact replica of an organism is produced. Some scientists have already produced clones of animals; Dolly the sheep is one of the many examples of DNA cloning. Cloning is a natural process‚ many living things only need one parent to reproduce‚ this process is called asexual reproduction; for example single-celled bacterium use this process. The new bacteria inherits its genes from only one parent‚ this means

The amazing advances in health science‚ DNA is transforming the way in which criminal investigations and trials are carried out. DNA evidence and its importance can rest on a single fact: Every individual’s DNA is unique. A person’s DNA profile can be used similar to a fingerprint to link suspects to crime scenes and its victims. DNA profiling—which is also called DNA fingerprinting or even DNA typing—has been responsible for overturning verdicts and saving innocent people from execution. The process

The Harmful Effects of Genetically Modified Organisms Genetic Engineering has been around since the 1970’s‚ but the process has become more complicated and ambiguous over time. A genetically modified organism‚ or GMO‚ is a plant‚ animal‚ or microorganism that has been produced to overcome any natural restrictions (Happiness). It encompasses eradicating the DNA‚ manipulating it‚ and then reinserting it into the original or alternative organism (Executive). Although GMO’s have some benefits‚ their

on on studying DNA by using a technique called X-ray diffraction. Her expertise was the X-ray diffraction mostly of proteins and lipids in a solution on DNA fibers. Franklin and a student‚ Raymond Gosling‚ took pictures of DNA and made the observation that there are two forms of DNA; the “A” form‚ which is dry and the”B” form‚ which is wet. One of their pictures of this observations‚ known as Photograph 51‚ became famous and was analytical evidence in discovering the structure of DNA. the photograph

The upper most strand is the (coding strand) DNA base sequence (triplet) of the gene codes for synthesis of a particular polypeptide chain. The second strand is the mRNA base sequence (template strand used for copying) codon of the transcribed mRNA. The process for going from the upper stand to the second strand is called Transcription and involves an enzyme called polymerase. The polymerase attaches to the promoter region (start codon) and reads the nucleotide base sequence until it gets to a termination

Roles of DNA and RNA in the Human Body and Medicine Anatomy and Physiology 1 Dr. Joy Henry Schonathan Crews 3/20/2015 Roles of DNA and RNA in the Human Body and Medicine Introduction Deoxyribonucleic acid (DNA) is the foreman of the body with a strict set of blueprints for what needs to be done in an organism’s cell and how.1 Each cell is encoded with a specific sequence of DNA which stores how it is to be made and reproduce. Ribonucleic acid (RNA) is the assistant to the foreman
