YOUR NOTES UNIT 2 NOTES DNA (deoxyribonucleic acid) DNA Functions • Stores genetic information and copies itself (replication) to pass on the information • Contains genes (instructions to make proteins) • Instructs cell’s activities DNA Structure • DNA is a polymer of nucleotides • Chromosomes (DNA strand + associated proteins ie. Histones wrap DNA around like a spool = condensed chromatin) ↓ genes (sections of a chromosome that codes for a protein) ↓ nucleotides (3 parts:

“Should we manipulate the DNA of bacteria?” This is a question that has no definite answer‚ but a limitless amount of controversy. Since DNA is the code within each and every cell that instructs them on how to function and bacteria are rapidly reproducing microbes‚ genetic engineering is something to be considered. In fact‚ Bacteria were the first organisms to be genetically engineered. Modifying or manipulating the DNA of microbes and bacteria should continue to be allowed because it can be used

Roles of microbes in DNA research Activities of microorganisms are very important to almost every sector of concern to mankind. From a perusal of the foregoing topics‚ one can find applications (uses) of microorganisms to agriculture‚ forestry‚ food‚ industry‚ medicine‚ and environment. The scope and significance of microbiology has enlarged manifold‚ particularly when importance of environment was realised globally and the word environment was used in a much wider sense in terms of totality to

In the past of the United States‚ many companies have taken these aspirations so far as to incite legislation intended to protect the rights of individuals from those of a business. Laws such as the Americans with Disabilities

Understanding the Functions of Proteins and DNA Ingrid Waldron‚ Biology Department‚ University of Pennsylvania‚ 2012 These key concepts and activities are suggested as part of an introductory unit on biological molecules (or as an introduction to a unit on molecular biology). The overarching goal is to help students understand that proteins and DNA are not just abstract concepts in biology textbooks but rather crucial components of our bodies that affect familiar functions and characteristics

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. * * There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding
