Document Summary
As it goes it unwinds dna, makes a bubble, then reseals as it goes. As it goes along the transcription unit rna is transcribed and spit out of the promoter. It keeps going along until it hit the termination point, where the transcription ends and the promoter leaves the strand, breaking off the rna strand. These experiments led to the one-gene-one polypeptide hypothesis, Mendel proposed a model to explain how traits passed from parent to. Morgan established that genes are on chromosomes. Meselson and stahl described how dna is copied. How is the information stored in genes and converted to stuff. Has it"s own enzymes, processes and not used for dna. From transcription, but has its own enzymes. Mrna covered with ribosomes to prevent it from being. Put on a 5" cap on 5" end and a poly-a-tail on the (cid:885)" end. Introns are spliced off, then the exons are stitched together.
