Document Summary
Rna can do enzymatic things cause single stranded and can form tertiary structures. Export if translated, needs to move out of nucleus. Quality defective or non functional rna can get degraded before translated. All regulate how much protein you end up with basically. If were doing a lot of studies on prokaryotes then ya they would have seen this. Aa refer in order directly to protein introns were not apparent. Compared dna of a gene to processed mrna produced from gene introns are usually larger than exons. Hybridized with rna should o(cid:374)l(cid:455) (cid:271)i(cid:374)d se(cid:395)ue(cid:374)(cid:272)e that"s (cid:272)o(cid:373)ple(cid:373)e(cid:374)ta(cid:396)(cid:455) Electron micrograph = 1st pic, 2nd = ribbon diagram found some dna forming loops (introns), exonic bound to mrna sequences in dna not in rna. Now defined as last point there are genes and other functional units in introns ligated back together = exons, not = introns snorna = modification/processing of ribosomal rna.
