Prokaryotic vs eukaryotic transcription transcription is a process by which the genetic information present in the dna is copied to an intermediate molecule rna the sequence in the rna is complementary to that of the gene which is transcribed and thus the rna retains the same information as the gene itself. The anatomy of a bacterial cell prokaryotic cell structure prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do instead prokaryotic cells have a nucleoid region which is an irregularly shaped region that contains the cells dna and is not surrounded by a nuclear envelope some other parts of prokaryotic cells are similar to those in . Ubiquitin like proteins ubls are a family of small proteins involved in post translational modification of other proteins in a cell usually with a regulatory function the ubl protein family derives its name from the first member of the class to be discovered ubiquitin ub best known for its role in regulating protein degradation through covalent modification of other proteins. The 5 untranslated region 5 utr also known as a leader sequence transcript leader or leader rna is the region of an mrna that is directly upstream from the initiation codonthis region is important for the regulation of translation of a transcript by differing mechanisms in viruses prokaryotes and eukaryoteswhile called untranslated the 5 utr or a portion of it is sometimes
