Nucleoside phosphoramidite

A nucleoside phosphoramidite is a tiny little building block that scientists use to make longer strands of DNA in a lab. Imagine you are building a tower with blocks made of different colors. Each time you add a new block, you need to make sure it fits and lines up with the others. The nucleoside phosphoramidite is kind of like a new color block that can be added onto a DNA strand. It has a special chemical structure that lets it "stick" or "link up" to the other blocks in the structure. Using these tiny little building blocks, scientists can create custom-made DNA strands for various purposes such as research or medicine.
