Whereas RNase E plays a key role in the degradation of mRNA and the processing of tRNA and rRNA in E. coli, the biological functions of RNase G appear more limited. We report here that this difference in function is not merely a consequence of the significantly lower cellular concentration ...
Learn the difference between DNA and RNA, learn about the 3 types of RNA and their functions and understand the structure and function of mRNA, tRNA and rRNA. Related to this Question A) Distinguish DNA from RNA, what is the same, what is different? B) What is th...
rRNA is somewhat different. All rRNA is derived from one monster of an rRNA strand some 13,000 nucleotides long. After a number of chemical modifications, this strand is cleaved into two unequal subunits, one called 18S and the other labeled 28S. ("S" stands for "Svedberg unit," a measu...
As an RNA cytidine acetyltransferase, NAT10 catalyzes the formation of N4-acetylcytidine (ac4C) modification of mRNA, rRNA, and tRNA to regulate ribosome biogenesis [6,7,8,9,10]. In addition, NAT10 participates in multiple cellular processes through its lysine acetyltransferase activity toward non...
to the next, and that every human being's DNA is unique (and therefore is a bad idea to leave at a crime scene). But for all of DNA's notoriety, RNA is a more versatile molecule, coming in three major forms: messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). ...
To understand the relationship between thegenomeand the functioning of cells, scientists have sought to study the products of the genome, namely proteins and expressed RNAs, such astRNAandrRNA. Proteomics is the study of the set of proteins in a cell or tissue, and it includes details on prot...
Translation regulatory mechanisms that impact on stem cell function include mTOR signalling, ribosome levels, and mRNA and tRNA features and amounts. Understanding these mechanisms important for stem cell self-renewal and differentiation may also guide our understanding of cancer grade and metastasis. ...

RNA Polymerase IINucleusTranscribes mRNA which is then translated into proteins in the ribosome. RNA Polymerase IIINucleusTranscribes transfer RNA (tRNA) and 5S rRNA. tRNA helps decode mRNA in the ribosome. 5S rRNA is a ribosomal RNA important for translation. ...
