The National Center for Biotechnology Information (NCBI) is like a big library that holds lots of information about living things, like plants and animals, and how they work. Scientists and doctors from all over the world can visit this library and use the information to learn more about different things or to help find ways to help people who are sick.
Just like how you have different books at school for different subjects, the NCBI also has different kinds of information about living things. Some of the things you might find in the NCBI library include the different parts of a cell, the way genes work and the different types of diseases that affect people and animals.
To help people find the information they need more easily, the NCBI also has computer programs called databases that store and organize all of the information. This way, when someone wants to learn about a certain type of cancer or a particular kind of animal, they can quickly find all the information that the NCBI has collected and organized about it.
In addition to holding all of this information, the NCBI also works on developing new ways to use it. They might develop computer programs to help doctors diagnose diseases more easily, or they might work on creating new drugs that can treat illnesses more effectively.
Overall, the NCBI is an important place where scientists and doctors can find and use information to help them learn more about why living things work the way they do and how to help people who are sick.
