lac operon 1. Hello! Sorry to hear about your kid. . I was looking through the outlines and there were a few answers i couldnt find in the book or in our notes. . I couldn't find info on the questions from study guide 11 about antibodies *I didn’t talk about antibodies. Instead, this is referring to antibiotic resistance. When dealing with two bacterial strains, one donor and one recipient, we usually have to eliminate one with antibiotics to determine what type of recombination has occurred between the two strains (in conjugation and transduction). and interrupted mating *under supplemental information “conjugation and mapping of bacterial genes”. A mating to determine the map of bacterial genes is done between an Hfr and F- strains. The example of that type of mating in the supplemental information is called an “interrupted mating” and that is referred to in the information. Write back with any specific questions about interrupted matings. If I wrote the information here, I’d just be re-writing the supplemental information. and transduction mapping. I also could not find info on cotransduction vs cotransformation and there frequency of genes. *This is also in the supplemental information and in your notes. “Transformation, transduction and gene mapping”. Again, write with more specific questions. Also, on study guide 12, there is a lot of information on trp and the notes i have do not cover all the questions. Such as what the function of the termination loop in the attenuation, *This signals termination of transcription what is the function of the antitermination loop, *This signals RNA polymerase to continue transcription. why trp is a corepressor, *trp binds to the repressor and the conformational change of the repressor allows it to bind to the operator. Pg. 370 box 17.1 is basic information on the trp operon. The rest is in the supplemental information. and does the operator region of the trp operon encode a protein. *No My last question is if the lacO is the lac operon. *LacO is the lac operator. If you could answer anything you can or set me in the right direction to find the info that would be greatly appreciated! Thanks for your time! 2. I know that lysozymes break up the cell membrane when its time for the lytic phages to exit, but it there anything else that specifically causes the cell to lyse? I was thinking that possibly the cell's own DNA has been so badly replaced/redirected that it can't mobilize the

mechanisms necessary to rebuild the membrane. Also, maybe the enzyme has a long lifespan and a specificity designed to keep it actively degrading the membrane and prevent the cell from repairing? Or maybe just plain osmosis results in flooding of the cell, bursting it? I tried to find specific info in the text, but it just covered the phages' exit, not the plight of the cell. Thank you so much!
