DNA Analysis Aids in Classifying Single-celled Algae


September 19, 2012

image of micro-algae called Symbiodinium For nearly 260 years--since Carl Linnaeus developed his system of naming plants and animals--researchers have classified species based on visual attributes like color, shape and size. However, in the past few decades, researchers have found that sequencing DNA can more accurately identify species. A group of single-celled algae--Symbiodinum--that live inside corals and are critical to their survival--are only now being separated into species using DNA analysis. Full Story
