Thanks for understanding my frustration everyone!!!

Debbie, I'm a PSYCHOLOGY major!!! I have to take this dumb class as a depth education general.

Sky, YUP he has tenure!! And he completely misundertsood my question. For those of you who will get totally bored by talk about DNA, you can stop reading here lol. Ok, so a codon is a grouping of 3 nucleotides in mRNA that codes for one amino acid. Most amino acids can be coded for by 4 different codons. The group of 4 codons that can all code for the SAME amino acid is referred to as that amino acid's codon quartet or codon family. My professor made the mistake of thinking that "codon quartet" referred to a codon being composed of 4 nucleotides, rather than a quartet of codons. This is ridiculous because codon quartets/families are discussed in the chapter, and are a CRUCIAL part of understanding wobble pairing!!! Apparently prof. didn't study wobble pairing, as he clearly stated above. Therefore, he misunderstood my question and told me that I WAS THE ONE WHO DID NOT UNDERSTAND- quite WRONG. And THEN chided me for not knowing intuitively that he would not expect me to understand these concepts in the chapter.

Oh, and he has gone on rants about how he's been teaching for many years and has this fool-proof and complicated grading system which he will not explain to us because he knows what he's doing and it's his job not ours to interpret grades... blah, blah, blah. Not a d--- thing any of us can do about it because we need this class for graduation and the guy has tenure so noone would listen if we did complain. In fact, he's a retired professor who has returned.

GRRRR.....

Thanks for letting me rant again
