High schools across the United States rarely offer bioinformatics due to its recent emergence and the need for extensive resources and equipment. However, this year Honors Bioinformatics debuted as a science elective for students who have completed one semester of biology, taught by science teacher Zane Moore.
After a Harker family donated an Illumina DNA sequencer in the summer of 2023, science department chair Anita Chetty pictured a course that delved into the essentials of DNA sequencing, the technique of determining the exact order of nucleotides in a DNA molecule.
Dr. Moore followed that vision and developed a class curriculum where students learn about the sequencing process and apply their understanding in labs, like analyzing tumor sequences and assembling the genome of a glowing millipede. He hopes that students can apply the knowledge and experience gained from bioinformatics to various fields.
“I’ve always been interested in using computational biology and mechanisms to solve biological challenges, and I thought that this new class would be the perfect opportunity,” Honors Bioinformatics student Krish Nachnani (11) said. “In the fields of ethics and biology, it’s important to be using these new machine learning and computational tools to further the field.”
Bioinformatics relies heavily on computer science to make sense of collected data to reach meaningful conclusions. DNA sequencers generate roughly 100 billion gigabytes of raw text, which is impossible for a human to manually interpret. Through this course, Dr. Moore hopes that students will be able to understand natural phenomena by generating targeted questions and methods to make sense of the vast amounts of data produced by sequencers.
“Sequencing is an easy thing to throw around, but sequencing with intention about what you’re trying to test, that’s what I want to teach,” Dr. Moore said. “It’s not just like, ‘Oh, look at this, let’s throw it in the sequencer.’ It’s saying, ‘Using the scientific method, I have a hypothesis. This pumpkin got damaged here. Maybe we can see something about the DNA at this damaged spot.’”
In this semester’s overarching lab project, students selectively mutate E. coli. by placing colonies in multiple environments, like UV radiation and antibiotic mediums. At the end of the semester, two winners are selected: the E. coli strain that can survive best in a mystery environment and the one that has mutated the most without dying.
Senior Juliana Li, who is taking the course this semester, appreciates how bioinformatics goes beyond traditional subject boundaries, allowing students to apply their diverse skills for applications in real-life situations.
“Usually, we do pure math, pure biology or pure computer science,” Juliana said. “Since bioinformatics is the intersection of biology, computation, math and computer science, it’s just super cool to see how those things combine and how it can make more of a real world difference by integrating the techniques of all of these disciplines.”
