WebA cistron is a section of a DNA or RNA molecule that codes for a specific polypeptide in protein synthesis. Prokaryotic genes are called polycistronic because the mRNA codes … WebIn eukaryotes, the transcript of a protein-coding gene is called a pre-mRNA and must go through extra processing before it can direct translation. Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the …
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.
