DNA sequencing From Wikipedia‚ the free encyclopedia [pic] The term DNA sequencing refers to sequencing methods for determining the order of the nucleotide bases—adenine‚ guanine‚ cytosine‚ and thymine—in a molecule of DNA. Knowledge of DNA sequences has become indispensable for basic biological research‚ other research branches utilizing DNA sequencing‚ and in numerous applied fields such as diagnostic‚ biotechnology‚ forensic biology and biologicalsystematics.

is that RNA uses uracil instead of the thymine in DNA. DNA replicates itself and RNA is synthesized from RNA on an as-needed basis. Their stability and reaction is also different. DNA is more stable and less reactive than RNA because of the deoxyribose sugar’s C-H bonds. It is stable in alkaline conditions; DNA has smaller grooves‚ which makes it harder for enzymes to “attack.” RNA is more reactive because of the ribose sugar’s C-OH‚ hydroxyl‚ bonds. Unlike DNA‚ it is not stable in alkaline conditions

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides
