Are UTRs Introns? UTR or untranslated region is a nucleotide sequence found on each side of the mature mRNA molecule. Meanwhile, the intron is a non-coding sequence found within the gene between exons. So, this is the key difference between UTR and intron. UTRs are not spliced off while introns are spliced off. Is UTR
What Is The Core Enzyme In RNA Polymerase? The Escherichia coli RNA polymerase (RNAP) is a multi-subunit enzyme composed of five subunits including α (two copies), β, β’ and ω subunits. These five subunits form the RNAP core enzyme responsible for RNA synthesis using DNA as template and ribonucleotide (rNTP) as substrate. Which of the
What Turns Off Transcription By Binding To The Operator? In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes
What Do You Mean By Regulation Of Gene Expression? Gene regulation is the process of controlling which genes in a cell’s DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. What
