Skip to 0 minutes and 9 seconds Millions of bacterial genomes are sequenced every year, producing a vast amount of data that needs to be analysed, explored, and interpreted. The study of bacterial genomes through the use of bioinformatics has helped researchers understand what turns bacteria into deadly pathogens. Have you ever wondered what researchers do with the sequencing data? How do they read these encoded messages? How do they identify which part of the DNA is responsible for pathogenicity or antibiotic resistance? I am Dr. Anna Protasio. I am Dr. Christine Boinett. And I am Martin Aslett. Here at the Wellcome Sanger Institute, we use genome sequencing to understand more about bacteria and to improve human health.

Skip to 0 minutes and 49 seconds In this course, you will learn how to access DNA data, how to interpret protein sequences from DNA, and how to do similarity searches on public databases. Together, we’ll learn how to use these revolutionary bioinformatic tools and databases to decipher the roles bacterial genes play in biology and disease. This course is for people who want to understand bioinformatics and to use these tools to answer biological questions. By the end of this course, you will be able to carry out similarity searches on public repositories and extract genome protein sequences from databases. You will also learn how to use online tools to understand protein function through similarity searches.

Skip to 1 minute and 28 seconds Join us on this fascinating voyage that will take us from gene sequences, homology searches, through to protein function.

Who is the course for?

The course will be of interest to undergraduates, post-graduates, researchers, bioinformaticians, biomedical researchers, microbiologists, healthcare professionals and all those who are interested in learning about the underlying mechanisms of bacterial disease, DNA sequences and protein data, or how to use online analytical tools to probe genomes.

The topics covered in this course are applicable to the genomes of all organisms. It is not essential to have previous knowledge or experience in bioinformatics. Scientific terminology is explained. The opportunity to use online computational tools in the context of bacterial genomes will also be of interest to teachers and their 16-18-year-old science and computing students.

What software or tools do you need?

No specific software, hardware, or other resources are required.
