Biology - February 2007

Transcription of RNA from DNA has alot of amazing steps that amazed me.One of them is that during the proccessing of m-RNA primary transcript,the introns are edited out.My question is if these codons are edited out in this step(they will not be translated) so what is the purpose of having them at all?
Another amazing things :why there is one codon for start and there are three codons for stop?What do you think the resons?And what will happen if there are the same number of codons for both the start and the stop?
or if the opposite happen( 1 codon for stop and 3 for start)????

Litmus milk tests bacteria for several things: peptonization, catabolism of carbohydrates, lactose fermentation, etc. An uninoculated llitmus milk tube is light purple in color. It will turn pink under acidic conditions, purple under alkaline conditions, and white if reduction of the litmus has occurred.

Is it possible for a bacteria to test positive for both acid production and reduction? Please explain thoroughly, and also note what any results might look like.

are we the end of line in evolution? does nature has another ace up its sleeve, a better one? have we interfered with nature to such an extent to have confused it? looks like it has to clean the slate to write something else.
