Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine‚ Guanine‚ Cytosine and Thymine. These bases

and the discovery of DNA Ralf Dahm* Max Planck Institute for Developmental Biology‚ Department 3 – Genetics‚ Spemannstr. 35/III‚ D-72076 Tubingen‚ Germany ¨ Received for publication 5 October 2004‚ revised 17 November 2004‚ accepted 20 November 2004 Available online 21 December 2004 Abstract Over the past 60 years‚ DNA has risen from being an obscure molecule with presumed accessory or structural functions inside the nucleus to the icon of modern bioscience. The story of DNA often seems to begin

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 Worksheet Trisha McCabe SCI/230 May 8th 20132 Chandreyi Basu‚ PhD Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA made up of units called nucleotides‚ nucleotides are made up of three molecules components‚ a nitrogen base‚ a sugar‚ and a phosphate (Simon‚ Reece‚ Dickey‚ 2010). The nucleotides are joined together by bonds between the sugar of one nucleotide and the phosphate of the next producing

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

DNA is a double helix molecule that contains information that is used to make up a person’s body. DNA controls every aspect of a person’s body from their eye and hair color‚ height‚ and other features. DNA’s specific and unique characteristic can be crucial when solving a crime. DNA can be used to convict a suspect or exonerate an innocent person. When DNA is found it is even more important that is handle properly to ensure proper identification and accuracy of testing. The evolution of DNA technology

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

DNA fingerprinting is a way of identifying a specific individual‚ rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology‚ it has been around since at least 1985‚ when it was announced by its inventor‚ Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal

have made the use of DNA in forensic science possible. In the past twenty years specifically‚ there have been many extraordinary discoveries in the fields of science that have led to the advancement of procedures in forensics. Before DNA testing‚ the most accurate way of identifying people was to match the blood types of suspects with blood found at the scene of the crime. Considering the lack of variability of this procedure‚ it is no surprise just how important the use of DNA in forensics has become

Discuss the epidermal and dermal layer of skin and how each relates to the permanence of fingerprints. The outer layer is known as the epidermis‚ and the inner layer is known as the dermis. The bottom of the epidermis‚is adjacent to the dermis‚ is the generating layer of the epidermis and it is in this layer that new cells are formed. The skin is one of the largest organs in the body. The epidermis has many smaller layers. The dermal layer is the growth layer of skin and feeds the epidermis
