R rna is synthesized in 258581-Where is rna made

The three major types of RNA that occur in cells are rRNA, mRNA, and transfer RNA (tRNA) Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA 372 viewsThe structure of RNA is basically a repeating chain of ribose and phosphate moieties, with one of the four bases attached to each riboseIn this templating scheme, the DNA base T specifies A in the RNA, A specifies U, C specifies G, and G specifies C Synthesis of RNA is usually catalyzed by an enzyme RNA polymerase, using DNA as a templateThe structure of RNA is basically a repeating chain of ribose and phosphate moieties, with one of the four bases attached to each riboseIn this templating scheme, the DNA base T specifies A in the RNA, A specifies U, C specifies G, and G specifies C Synthesis of RNA is usually catalyzed by an enzyme RNA polymerase, using DNA as a template

Where is rna made

Where is rna made-Each subunit comprises one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins (rprotein or rProtein) Different rRNAs present in the ribosomes include small rRNAs and large rRNAs, which denote their presence in the small and large subunits of the ribosomeNucleic Acids like DNA, RNA contains only Nucleotides and function as genetic material wherein r RNA (ribosomal RNA) is a type of RNA, which is a nucleic acid Thus synthesised in Nucleolus Option 1) Lysosomes This option is incorrect Option 2) Nucleolus This option is correct Option 3) Nucleoplasm This option is incorrect Option 4

Transcription

RNA is synthesized in the nucleus through a process called "transcription" This RNA leaves the nucleus through nuclear pores and enters the cytoplasm Which is the largest RNA among mRNA, rDifferent from DNA base pairing, Dadenine pairs with Ruracil Through another portal in the RNA Polymerase, emerges the developing mRNA Once a few ribonucleotides are synthesized by RNA Polymerase, the sigma protein is removed Once the sigma is removed, it can be reused to initiate transcriptionJozef J Bujarski, in Encyclopedia of Virology (Second Edition), 1999 Recombination in RNA Viruses RNA viruses utilize RNA as their genetic material The potential for variation of the RNA genome is very large owing to a high mutation rate (during copying by RNAdependent RNA polymerase) and to recombination

In bacteria, once RNA Polymerase transcribes a specific sequence of Rnucleotides from the DNA template strand, transcription ends (or terminates) When this sequence is synthesized, a section of the RNA bends back on itself forms a short double helix based on complementary base pairing This forms a RNA hairpin This hairpin forces the RNA toFrom the initial phase (t = 0 intercept) values for long and short RNA synthesis at each promoter, we observe that approximately one RNA is rapidly synthesized per OC in this initial phase 07 ± 02 (λP R (T7A1), 08 ± 02 (λP R (λP R), 09 ± 02 T7A1(T7A1), and 13 ± 04 (T7A1(λP R) Individual amounts of each RNA length synthesizedMolecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA The encoded rRNAs differ in size, being distinguished as either large or small Each ribosome contains at least one large rRNA and at least one small rRNA

RNA is an important molecule in cellular biology It controls many processes at the cellular level, including protein synthesis and some functions related to genetic coding Unlike DNA, which is known for its doublehelix shape, RNA is a singlestranded molecule It is usually found in nature as a single strand folded onto itselfRibosomal RNA (rRNA) is the catalytic component of the ribosomes Eukaryotic ribosomes contain four different rRNA molecules 18S, 58S, 28S and 5S rRNA Three of the rRNA molecules are synthesized in the nucleolus, and one is synthesized elsewhere In the cytoplasm, ribosomal RNA and protein combine to form a nucleoprotein called a ribosomeEach subunit comprises one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins (rprotein or rProtein) Different rRNAs present in the ribosomes include small rRNAs and large rRNAs, which denote their presence in the small and large subunits of the ribosome

Similarly, RNA recombination in nodaviruses, twopartite RNA viruses, occurs between RNA segments at a site, where the nascent strand could form a basepaired region with the acceptor template Such factors as template secondary structure and the similarity of the crossover sites to an origin of replication seem to influence the choice ofIn bacteria, once RNA Polymerase transcribes a specific sequence of Rnucleotides from the DNA template strand, transcription ends (or terminates) When this sequence is synthesized, a section of the RNA bends back on itself forms a short double helix based on complementary base pairing This forms a RNA hairpin This hairpin forces the RNA toRNA is synthesized in the nucleus through a process called "transcription" This RNA leaves the nucleus through nuclear pores and enters the cytoplasm Which is the largest RNA among mRNA, r
