Document Summary
Tom"s drop in: thursday at 1 and friday at 2 pm in rm 301 g ncb. Appointments also by email. thaffie@uwo. ca put 1002b in subject. The next few classes review many familiar aspects of gene expression and will highlight new understanding of: more trna base pair with itself. Why are there different terminator sequences, why do they have different efficiency: maybe they fold differently, their base sequences are different. Forces are stronger on the stem: maybe the terminator sequence can be longer, so efficiency is higher, the one that last longer (more efficient), might be more stable. The type of bonds between it, i. e. c-g bonds. Clicker question (1): which dna strand will be the template for gene b. Because we don"t know where the promoter is. Promoters have a direction, they point to a direction of transcription. They can only go from 3" -> 5".
