Ribonucleic acid (RNA) is a chemical compound that exists within cells and viruses. In cells, it can be divided into three categories: Ribosomal (rRNA), Messenger (mRNA) and Transfer (tRNA). While all three types of RNA can be found in ribosomes, the protein factories of cells, this art...
Describe the role/function of rRNA, tRNA, mRNA in reference to protein synthesis. What are the primary functions of protein? Explain the difference between DNA replication and RNA transcription. Explain the role of P and N nucleotides.
messenger RNA (mRNA) –It is the RNA that carries information from DNA to the ribosomes (site of protein synthesis) in the cell. The mRNA code sequences determine the amino acid sequence in the protein that is produced. ribosomal RNA (rRNA)– It incorporates into the ribosomes. transfer R...
The diversity of RNAs in the cell continues to amaze. In addition to the 'classic' species of mRNA, tRNA, rRNA, snRNA and snoRNA, it is now clear that the ... M Schmid,TH Jensen - 《Trends in Biochemical Sciences》 被引量: 541发表: 2008年 Conserved Stem II of the Box C/D Motif...
tRNA is also known as an adaptor molecule as it translates the codons present in mRNA sequences into amino acids. tRNA is only 70-90 nucleotides in length, making it the smallest out of the three main RNAs (mRNA and rRNA). The molecular weight of the tRNA molecule ranges from 25,000 ...
T he central role of RNARNA in translation has been accepted for more than 50 years, although classically the only known roles for RNARNA were as a template for translation (mRNARNA) or as part of the translational machinery (rRNARNA and tRNARNA). In 1989, S. Altman and T.?C?Cech ...

Regulation of mRNA translation offers the opportunity to diversify the expression and abundance of proteins made from individual gene products in cells, tissues and organisms. Emerging evidence has highlighted variation in the composition and activity of several large, highly conserved translation complexes...
Most of the vital cellular and enzymatic reactions likecellular respirationand translation of mRNA into proteins occur in the cytoplasm. It acts as a buffer and protects genetic materials as well as other organelles from damage due to collision or change in the pH of the cytosol. ...
YTHDF2 promotes mRNA decay. The C-terminus of YTHDF2 selectively identifies m6A-modified mRNA, while the N-terminus recruits the carbon catabolite repression 4-negative on TATA-less (CCR4-NOT) complex and forms bridges between the mRNA and the processing body, thus mediating the decay of selec...
