BIO 181 Lecture 1.6

Lecture 1.6: Cells and Chromosomes

Overview

NASA scientists and others designing experiments that look for life on other planets generally focus on the fact that life on Earth is cellular (in general). But there are two very different types of cellular life on Earth–prokaryotic and eukaryotic. Actually, there are 3, but here we focus on this particular classification. The key differences involve fundamental differences in anatomy and DNA organization, which we begin to explore here.
