    Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA? DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common‚ B form‚ is the structure most people have heard of. It consists of the right

    DNA is the common name for Deoxyribonucleic acid. This is made up of nucleic acids containing deoxyribose (sugar)‚ consisting of complex molecules‚ present in the chromosomes of all plant and animal cells‚ and carrying in coded form instructions for passing on hereditary characteristics. The DNA molecule takes the shape of a double helix‚ a simple structure that resembles gently twisted ladders. The rails of the ladder are made of pairs of nitrogen-containing nucleotides‚ which are subdivisions

    plasmid DNA and analysis of isolated plasmid Introduction: A plasmid is an autonomously replicating extra-chromosomal genetic element. In other words‚ this is a DNA molecule external to the bacterial chromosome that is able to replicate on its own and distribute its daughter molecules to daughter cells. You have successfully cloned a fragment of chromosomal DNA containing a tetracycline resistance cassette into a plasmid (pET11a). To this end you have (1) isolated total chromosomal DNA from your

    DNA STRUCTURE AND REPLICATION One may wonder how a single cell becomes two cells‚ and why this is ultimately important to life. For this essay‚ it would be much too difficult to discuss the process of cell division‚ which is the biological basis of life. That being said‚ this essay will examine more closely the precursor to cell division‚ also known as DNA replication. DNA replication is the process of copying a double-stranded DNA strand on a chromosome within a cell. The process‚ in its totality

    Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase support

    The DNA double helix model In 1953 James Watson and Francis Crick made a scientific breakthrough when they discovered the structure of DNA. From this structure they inferred that DNA contains information written in a genetic code‚ is passed from one generation to the next. This discovery was to be a key step in the genetics revolution DNA has four molecular building blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C). Purine base always pairs (by hydrogen bonding) with
