You want to test a hydroxylating agent that adds an -oh group for mutagenicity by doing the ames test. hydroxylamine adds -oh to cytosine, and hydroxylated c pairs with a instead of g. there are different types of his- auxotrophs that you can choose from in order to detect reversion to his+ prototrophs in response to a compound under test. what type of his- mutants do you need to use for testing hydroxylamine in the ames test?

Why is carbon ideal for making different compounds?

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
