WebEukaryotic RNA Processing: RNA splicing (RNA is called hnRNA - Heteronuclear RNA before splicing occurs) ¥Splicing is: ÐThe mechanism by which introns are removed. ¥Introns are intervening sequences - not expressed in proteins ¥Exons are retained in the mature mRNA molecules. Ðexpressing sequences WebIn prokaryotes, the primary mRNA transcript is functional as soon as it is synthesized. This is seen when ribosomes bind to the free 5′ end, even before the remainder of the molecule is transcribed. (Remember that synthesis is 5′ to 3′, so the 5′ end of mRNA is synthesized first.) camping berchtesgadener land mit hund

WebPlatelets are the smallest cell in the bloodstream, and one of the few anucleate cells (i.e., cells that circulate without a nucleus). Because of their small size and anucleate stature, platelets have historically been conceived of as "sacs of glue" that function solely to stop bleeding. Andrew Weyrich, MD, and his group made the seminal discovery that anucleate … WebIn eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs).
