BIOINFOMATICS

According to the National Human Genome Research Institute (NHGRI), bioinformatics is a subdiscipline of biology and computing that serves to acquire, store, analyze and disseminate biological data, mostly DNA and amino acid sequences. For example, to study how normal cell activity is altered during an illness, it is necessary to combine data relating to numerous compounds and interpret the changes. This is especially true for proteins, the building blocks of life.

In the beginning, the term bioinformatics did not have the same meaning, as it was applied to the theoretical study of biological processes. However, advances in computing and data processing have made it possible to sequence more and more proteins automatically, culminating in a milestone.Bioinformatics involves processing, storing and analyzing biological data.Creating databases to store experimental data.Predicting the way that proteins fold up.Modelling how all the chemical reactions in a cell interact with each other.Bioinformatics is a broad field and needs a diverse range of people with diverse skill sets. Programmers to write the computer programs to analyze all this data, database administrators to organize storing it all, biological scientists and statisticians to analyze the data, and web designers to produce sites and apps that scientists can use to search all this data.Bioinformatics allows researchers to perform experiments on a timeline that matters in a person’s lifetime. For example, during the coronavirus pandemic, researchers were able to sequence the virus’s genome, identify what was likely to be causing the virus to enter cells, and develop a vaccine based on the discovered genome within a matter of months. This would not have been accomplished if researchers had manipulated handwritten codes to find meaningful connections. Additional bioinformatic approaches are being used to identify and treat other diseases like diabetes and cancer.To glean significant findings from biological data, bioinformatics uses computer tools like data mining, pattern recognition, visualization, and machine learning. By combining domain science knowledge, statistics, and data science, bioinformatics researchers can create more targeted web lab experiments to more quickly home in on a specific area of research, such as creating a new drug. They can also comb through information from existing databases to discover the gene responsible for a disease or discover common immune responses to evaluate unknown pathogens.

Bioinformatics makes previously unthinkable areas of study possible through data management and analysis. Because bioinformatics tools can be used to sift through enormous amounts of data from multiple studies, they exponentially increase the usefulness of past data as researchers mine information to make new connections. This can be done using data from different parts of the globe and generated or analyzed by researchers who have never met.The tools can also be used to improve current experiments. Because of the relative ease of in silico experiments, researchers can iterate on their experimental design by using data analysis to determine targets to study or how many samples they need to make a statistically valid discovery. In addition, the tools can sort through scant data to better inform researchers as they make interpretations or identify never-before-seen protein sequences. And functional bioinformatics allows researchers to model these possible protein structures to determine their potential interactions within cells.

More complicated experiments are possible as technology gets more sophisticated, but there is a limit to how far bioinformatics can reach. Even though bioinformatics can transform enormous amounts of biological data into patterns humans can read and comprehend, biologists who have specialized in relevant fields are still required to interpret those patterns. Indeed, bioinformatics as a field often must bring researchers from many different domains together to communicate along every part of the experimental chain. Bioinformatics is a multidisciplinary field used in many life sciences, so it has numerous applications. It has led to advances in personalized medicine, adapting treatments to each person's genetics. It has had a fundamental role in pharmaceutical research, particularly in combatting infectious diseases, and in developing vaccines. It is applied to gene therapy, particularly in illnesses caused by individual genes that have been affected or inherited. Likewise, the comparison of genomic data adds to our knowledge of the evolutional history of life on Earth. The use of proteomics, metabolomics and genetics allows stronger crops to be developed that are more resistant to drought and insect pests.
