Splicing techniques are methods used to join two pieces of material, often in the context of fiber optics or genetic engineering. In fiber optics, splicing involves aligning and fusing the ends of optical fibers to ensure minimal signal loss. This can be done using mechanical splicing or fusion splicing, each with its own advantages and applications. In genetic engineering, splicing refers to the process of manipulating DNA sequences. Techniques like CRISPR allow scientists to cut and insert specific genes, enabling the modification of organisms for research or therapeutic purposes. These splicing methods are crucial for advancements in biotechnology and medicine.
