This page, while it is useful as a reference to see what is most heavily focused on in the class (I’d like to think, anyways), falls somewhat short if used as a general reference guide. Because of this, we have scoured the Web to produce a list of websites that provide background or extended information on a topic, in case something isn’t clear on this site. Note that these sites are given to me and placed directly on the page; if a link doesn’t work, report it to me, and I’ll fix it. I’ll resolve most non-functional links by myself given a little time. |

The Genetic Elements of Prokaryotes If you want to review some of the general features of the bacteria chromosome, the following website would be a good tool. The following website includes very basic information about DNA and the prokaryotic genome and would be a good information source for reviewing purposes. This website is fairly decent and gives a little information about the fertility factor and bacterial conjugation This website provides an informational outline that is very brief and does not include depth. It can be used to look over and review some facts. lac operon http://esg-www.mit.edu:8001/esgbio/pge/lac.html This link is really good for understanding the components to the lac operon using visuals and the operon works without mutations. http://www.ndsu.nodak.edu/instruct/mcclean/plsc431/prokaryo/prokaryo2.htm Can be used for information regarding induction in the lac operon and consititutive mutants. www.accessexcellence.org/AB/GG/induction.html Only provides a good visual for induction, but hardly gives an explanation. www.med.sc.edu:85/mayer/geneticreg.htm Includes distinctions between structural and regulatory genes, describes the operator and the inducer, and gives an explanation on catabolite repression. www.cat.cc.md.us/courses/bio141/lecguide/unit4/u4ib5.html#ind Provides a mediocre explanation of the operon, but provides good figures. ara operon www.mun.ca/biochem/courses/3107/Lectures/Topics/Ara_operon.html Gives a good and brief explanation of the operon’s struction and function. www.blc.arizona.edu/marty/411/Modules/arabop.html This website is similar to the previous website. http://bioweb.uwlax.edu/GenWeb/Molecular/Molecular_Biology_Syllabus/gene_articles. html http://www.biology.ualberta.ca/courses.hp/gen304/Adames/lec8_F01_NA.pdf This website is not as brief as the others, but it provides a better and detailed explanation of the operon, its positive regulation, and catabolite repression. trp operon www.uwec.edu/academic/curric/scalesjb/MolBiol/Trp%20operon%20at.../slide0001.ht ml http://web.indstate.edu/thcme/mwking/gene-regulation.html This website gives a good explanation and clear figures for the operon’s struction and attenuation. www.ndsu.nodak.edu/instruct/mcclean/plsc431/prokaryo/prokaryo3.htm Gives a very good explanation of the trp operon as a repressible system, its control, and its gene and gene function; however, it does not provide good visuals. http://www.blc.arizona.edu/marty/411/Modules/trpop.html This website provides in depth explanations of attenuation in the trp operon. Translation www.med.unibs.it/~marchesi/protsyn.html Provides an in depth discussion of translation, including tRNA structure and the Wobble hypothesis. www.accessexcellence.org/AB/GG/protein_synthesis.html Simply gives visualization to protein synthesis in general. www.indstate.edu/thcme/mwking/protein-synthesis.html This website covers about the same amount of information in the first link provided for translation, except this website seems better because the information is presented in a more orderly fashion and seems easier to understand. http://gened.emc.maricopa.edu/bio/bio181/BIOBK/BioBookPROTSYn.html This website includes a lot of information regarding protein synthesis, with very good visuals and explanations. http://www.inf.ethz.ch/~vonrohr/Courses/CompBio/Script/week1/BasicBiologyMain/no de8.html Gives an extremely brief explanation of transcription, translation, and protein synthesis. Transposons www.ultranet.com/~jkimball/BiologyPages/T/Transposons.html This website includes a clear definition of transposons. Mutations This website covers mutations and selection briefly and includes a very brief discussion of phenotypic consequences of mutations (the formation of auxotrophs and prototrophs). This link will help with bacterial genetic nomenclature, and clear up relations between genotypes and phenotypes. This website is a more detailed information sources than the previous website given about mutations. It provides more visual explanations and some clear definitions and brief charted explanations regarding the basis of mutations, including different types of mutations, the origin of mutations, and bacterial transformation and conjugation.
