Nucleoli also have other important functions like assembly of signal recognition particles and playing a role in the cell's response to stress.Translational regulation: Translational regulation refers to the control of the levels of protein synthesized from its mRNA. The corresponding mechanisms are primarily targeted on the control of ribosome recruitment on the initiation codon, but can also involve modulation of the elongation or termination of protein synthesis.Nuclear RNase PProtoplasm: Protoplasm is the living content of a cell that is surrounded by a plasma membrane. It is a general term for the cytoplasm.Ribonuclease L: Ribonuclease L or RNase L (for latent), known sometimes as ribonuclease 4 or 2'-5' oligoadenylate synthetase-dependent ribonuclease — is an interferon (IFN)-induced ribonuclease which, upon activation, destroys all RNA within the cell (both cellular and viral). RNase L is an enzyme that in humans is encoded by the RNASEL gene.Eukaryotic transcription: Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of RNA replica. Gene transcription occurs in both eukaryotic and prokaryotic cells.Buoyant density ultracentrifugation: Buoyant density centrifugation uses the concept of buoyancy to separate molecules in solution. Usually a caesium chloride (CsCl) solution is used, but in the general case it's usually approximately the same density as the molecules that are to be centrifuged.Ribonuclease T2: Ribonuclease T2 (, ribonuclease II, base-non-specific ribonuclease, nonbase-specific RNase, RNase (non-base specific), non-base specific ribonuclease, nonspecific RNase, RNase Ms, RNase M, RNase II, Escherichia coli ribonuclease II, ribonucleate nucleotido-2'-transferase (cyclizing), acid ribonuclease, RNAase CL, Escherichia coli ribonuclease I' ribonuclease PP2, ribonuclease N2, ribonuclease M, acid RNase, ribonnuclease (non-base specific), ribonuclease (non-base specific), RNase T2, ribonuclease PP3, ribonucleate 3'-oligonucleotide hydrolase, ribonuclease U4) is an enzyme.

DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.Internal ribosome entry site: An internal ribosome entry site, abbreviated IRES, is a nucleotide sequence that allows for translation initiation in the middle of a messenger RNA (mRNA) sequence as part of the greater process of protein synthesis. Usually, in eukaryotes, translation can be initiated only at the 5' end of the mRNA molecule, since 5' cap recognition is required for the assembly of the initiation complex.Cajal bodyMT-RNR2: Mitochondrially encoded 16S RNA (often abbreviated as 16S) is a mitochondrial ribosomal RNA (rRNA) that in humans is encoded by the MT-RNR2 gene.
