The main difference between prokaryotic and eukaryotic RNA polymerase is that prokaryotes have a single type of RNA polymerase, whereas eukaryotes have three main types of RNA polymerases Furthermore, prokaryotic RNA polymerase contains five subunits while in eukaryotes, RNA polymerase I transcribes rRNA genes, RNA polymerase II transcribes mRNA genes, and RNA polymerase III transcribes smallRibosomal RNA (rRNA), molecule in cells that forms part of the proteinsynthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein The three major types of RNA that occur in cells are rRNA, mRNA, and transfer RNA (tRNA)Numerous key discoveries in biology have emerged from studies of RNA (ribonucleic acid), including seminal work in the fields of biochemistry, genetics, microbiology, molecular biology, molecular evolution and structural biologyAs of 10, 30 scientists have been awarded Nobel Prizes for experimental work that includes studies of RNA Specific discoveries of high biological significance are
Ribosomal RNA Definition Ribosomal ribonucleic acid (rRNA) is the RNA component of ribosomes, the molecular machines that catalyze protein synthesisRibosomal RNA constitute over sixty percent of the ribosome by weight and are crucial for all its functions – from binding to mRNA and recruiting tRNA to catalyzing the formation of a peptide bond between two amino acidsTypes of RNA and their roles The type of RNA dictates the function that this molecule will have within the cell Aside from the coding region of messenger RNA (mRNA) molecules that will beAn RNA vaccine or mRNA (messenger RNA) vaccine is a type of vaccine that uses a copy of a natural chemical called messenger RNA (mRNA) to produce an immune response The vaccine transfects molecules of synthetic RNA into immunity cellsOnce inside the immune cells, the vaccine's RNA functions as mRNA, causing the cells to build the foreign protein that would normally be produced by a pathogen
Types of RNA Structure of RNA The primary structure of RNA is the same as that of DNA It is also a polynucleotide chain with 5′3′ sugar phosphate links But the sugar is ribose and generally it exists as a singlestranded molecule For that reason, it does not have the onetoone ratio between the complementary basesRNA A polymer of ribonucleotides, is a single stranded structure There are three major types of RNA m RNA,t RNA and r RNA Besides that there are small nuclear,micro RNAs, small interfering and heterogeneous RNAs Each of them has a specific structure and performs a specific functionTransfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins In addition to tRNA there are two other major types of RNA messenger RNA (mRNA) and ribosomal RNA (rRNA) By 1960 the involvement of tRNAs in the assembly of

Messenger RNAs, also known as mRNA, are one of the types of RNA that are found in the cell This particular one, like most RNAs, are made in the nucleus and then exported to the cytoplasm where the translation machinery, the machinery that actually makes proteins, binds to these mRNA molecules and reads the code on the mRNA to make a specific proteinA second type of RNA helps form the structure of a ribosome This type of RNA is called ribosomal RNA, or rRNA Remember that DNA and RNA differ slightly at the nucleotide level Therefore, theIf DNA is a protein "blueprint," then think of the RNA as the "architect" that reads the blueprint and carries out the building of the protein There are different types of RNA that have different functions in the cell These are the most common types of RNA that have an important role in the functioning of a cell and protein synthesis
