It is an important gene expressed in E. coli that represses the SOS response and also the expression of lambda lytic phase genes. UV light and damage to DNA is responsible for its breakdown and hen…

Introduction to gene regulationRegulation is all about decision making. tissues).Since the subject of regulation is both a deep and broad topic of study in biology, in Bis2a we don& 39;t cover every detail - there are way too many. Rather, as we have done for all other topics, we try to focus on (a) outlining some core logical constructs and questions that you must have when you approach ANY scenario involving regulation, (b) learning some common vocabulary and ubiquitous mechanisms and (c) examining a few concrete examples that illustrate the points made in a andb.

My learning of molecular biology ended in the early 90's (and with early 90's era information). While I don't aspire to be a molecular biologist, I do aspire to better understand modern approaches…

We're working on invertebrate hemolymph (blood) and we have found with flow cytometry (staining with DRAQ5) a cell-like population without nucleus but it has RNA production. Does anyone any exper…

Learning ObjectivesIdentify fungi that serve as foodHumans have collected and used fungi for thousands of years. Going out to dinner, you find fungi everywhere. It can be found in the Bleu Cheese used with your chicken wings or burger, to the yeast in the dough for your mushroom pizza.Edible mushrooms include commercially raised and wild-harvested fungi.

I tried to sowing roses from rose hips the first time. (In autumn I collected some rose hips random from different bushes in the neighborhood. I mixed the seeds while sowing.) Now the seedlings gro…
