One common use of open reading frames (ORFs) is as one piece of evidence to assist in gene prediction. Long ORFs are often used, along with other evidence, to initially identify candidate protein-coding regions or functional RNA-coding regions in a DNA sequence. The presence of an ORF does not necessarily mean that the region is always translated. For example, in a randomly generated DNA sequence with an equal percentage of each nucleotide, a stop-codon would be e… Web29 jul. 2024 · The solution: CRISPRa. CRISPRa libraries are an alternative tool that can be used for high throughput gain-of-function experiments andt avoid the pitfalls mentioned above. The synthetic RNA technology (instead of lentivirus) allows surety of a consistent stock concentration from well-to-well. Delivery into cells is a simple transfection, so ...
