WebAug 27, 2024 · Only recently has it been recognized that the transcriptome of bacteria and archaea can be spatiotemporally regulated. All types of prokaryotic transcripts—rRNAs, tRNAs, mRNAs, and regulatory RNAs—may acquire specific localization and these patterns can be temporally regulated.

WebOct 1, 2024 · In a polycistron, two or more gene sequences are controlled by a single promoter (Fig. 1A ), which enables the synthesis of polycistronic mRNA. A typical polycistronic mRNA consists of cistronic regions and intercistronic regions (Fig. 1A ). In most cases, each cistron gene has a Shine-Dalgarno (SD) sequence upstream of its start codon. WebAn intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word intron is derived from the term intr agenic regi on, i.e. a region inside a gene. [1] The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts. [2]
