Web[See a diagram of the bases] The picture below shows DNA being transcribed by many RNA polymerases at the same time, each with an RNA "tail" trailing behind it. The polymerases near the start of the gene have short RNA tails, which get longer and longer as the polymerase transcribes more of the gene. WebIn prokaryotic cells, ribosomes are typically about 70 S (MW about 2.7 x 10 6) and are formed from 30 S and 50 S subunits. The complete ribosome formed by combination of the subunits is also referred to as a monomer. Although ribosomes from both prokaryotic and eukaryotic sources are about 30 to 45% protein (by weight), with the remainder being ...
