The Bioinformatics is a discipline that allows applying tools of computer science to the study and management of data in biology. Various fields of knowledge interact in its field, such as computer science, statistics and chemistry.

The medicine makes use of the information provided by the bioinformatics research to develop and improve prevention efforts, diagnosis and treatment of ailments and diseases. Bioinformatics, in this framework, can be very useful for the analysis of very small scale elements, such as proteins and genes.

The development and application of computational resources for the management of medical or biological data is the axis of bioinformatics. Its purpose is to create the tools that allow obtaining, storing, analyzing and displaying this type of data.

It's common for the concept of bioinformatics to be confused with other notions. The computational biology, for example, is focused on the creation of theoretical models and simulation techniques. The biocomputation, meanwhile, aims at producing computers (PCs) having components of biological type or operating as a living being.

A simplified definition indicates that bioinformatics is the creation of computer tools to analyze and manage data of interest to biology. Bioinformatics can also be understood as a discipline that uses and processes information to understand biological aspects.

In addition to all of the above, we can underline the fact that bioinformatics has three clearly defined objectives such as:

- Resources and tools that can help with data analysis.
- Organize all the information in what are databases or databases. In this way, the researcher will be facilitated not only to access it but also to analyze and work with it for their projects to reach new results and conclusions.
- Use the aforementioned data and resources to analyze them thoroughly and proceed to interpret the results.

The annotation (marking) of genes, the analysis of the sequences of deoxyribonucleic acid ( DNA ) and the study of gene expression and proteins are some of the objects of study of bioinformatics.

No less important is to know that bioinformatics is currently used in many ways. However, there are several applications that are made of it that are the most interesting and even the most useful. We are referring to the following:

- To proceed with the design of medications, which will have a very positive effect on human beings who can find a suitable drug for their pathologies.
- To look for similarities between what are different molecules. And that's relevant within the studies that are undertaken on the evolution.
- To study thoroughly and analyze what climate change is. A job is really important for humanity and the environment in general. Specifically, this function is one of the most valuable in recent years, due to the increased concern about the aforementioned climate change.
