Document Summary
Ls7a week 5 tuesday notes macromolecule deoxyribonucleic acid (dna), a linear polymer of four different subunits. double helix, is composed of two strands coiled around each other to form a sort of spiral staircase. Some of the information in dna encodes for proteins that provide structure and do much of the work of the cell. Information in dna is called genetic information, and it is organized in the form of genes, as textual information is organized in the form of words. Experiment http://www. macmillanhighered. com/brainhoney/resource/6716/digital_first_content/trunk/test/morri s2e/asset/img_ch3/morris2e_ch03_fig_03_01cd. jpg (data was used from background) Conclusion one strain of bacteria (nonvirulent) can be transformed into another (virulent) by an unknown molecule from the virulent cells. In other words, the unknown molecule carries information that causes virulence. Transformation: the conversion of cells from one state to another, as from nonvirulent to virulent, when dna released to the environment by cell breakdown is taken up by recipient cells.
