Quiz: How Does Your Knowledge of Life’s Building Blocks Stack Up?

1 comment

Cells are the smallest units of life, providing structure and function for all living things, from microorganisms—like bacteria, algae, and yeast—to humans. They come in a wide range of sizes and shapes, and they’re complex machines with many smaller components that work together.

Some NIGMS-funded researchers use imaging techniques to peer inside cells, examine their structures, and study how they divide, grow, communicate, and carry out basic functions. Others use biochemical and genetic tests to study how cells interact with their environments, including those that may be toxic. Understanding cells’ biological processes helps to keep us healthy and identify new methods for treating disease.

Take our quiz to test how well you know cells. Afterward, check out our Studying Cells fact sheet and other blog posts on cell biology.

Recent advances in computing enable researchers to explore the life sciences in ways that would have been impossible a few decades ago. One new tool is the ability to sequence genomes, revealing people’s full DNA blueprints. The collection of more and more genetic data allows researchers to compare the DNA of many people and observe variations, including those shared by people with a common ancestry.

Sohini Ramachandran Link to external web site, Ph.D., is director of the Center for Computational Molecular Biology and associate professor of biology and computer science at Brown University in Providence, Rhode Island. She is also a recent recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE). Dr. Ramachandran researches the causes and consequences of human genetic variations using computer models. Starting with genomic data from living people, her lab applies statistical methods, mathematical modeling, and computer simulations to discover how human populations moved and changed genetically over time.
