Introduction to genetics. For other uses‚ see DNA (disambiguation). The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structure of two base pairs are shown in the bottom right. The structure of part of a DNA double helix Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates

2011 What is Nano DNA Sequencing? DNA strand is threaded through a nano-pore and its sequence is identified from fluctuations in ionic current. (9) Trick is to figure out how to slow the strands movement through the opening so the base pairs A‚T‚C ‚& G can be read. (1) Example: graduate Brown student attached DNA strand to a bead using an electric field to drive the DNA to the pore. The DNA was too large for the pore‚ so‚ the bead was stuck in the hole with the attached DNA strand suspended

EXTRACTION OF DNA FROM ONIONS ABSTRACT The purpose of the experiment was to experience firsthand the isolation of DNA form a plant tissue without destroying its structure and sequence. A white onion was used for the experiment. After several processes‚ DNA isolate was the visible result. Different chemical tests were performed on the DNA isolate‚ namely: Dische Test‚ Murexide Test‚ Wheeler-Johnson test and Test for Phosphate. Visible results were then noted.

T.O.K. Essay To what extent does the scientific method allow us to uncover truth? The scientific method consists of five steps: first‚ observing and recollecting information. Second‚ creating or formulating a hypothesis. Thirdly‚ scientists experiment‚ with the information and the observations they have made so as to reach to a conclusion‚ which is the fourth step. Finally‚ the last step consists in the communication‚ which is when you tell society about a new discovery or theory and the

Discussion Although only the extraction of strawberry DNA was performed in this lab‚ this section will address the roles of each step taken and the reagents used during the extraction of DNA from animal tissue as well‚ and compare it to the steps taken in the strawberry protocol. As described in the procedure using strawberries‚ the first step was to mash them into pulp using a mortar and pestle. The main goal from this physical disruption was to break the solid material consisting of any connective
