The most common organism in the world's oceans -- and possibly the whole planet -- harbors a virus in its DNA. This virus may have helped it survive and outcompete other organisms. The most common ...

What smaller elements make up the complex DNA molecule, how are these elements arranged, and how is information extracted from them? This unit answers each of these questions, and it also provides a ...

While mutations can arise in the genome and have little consequence, sometimes they are beneficial and selected to remain in an organism. In most cases, genetic errors have negative consequences for ...

Researchers have identified the mechanism used by the helicase ring to thread around and separate entwined DNA strands in the replication process. DNA replication is a complex process in which a ...

Complex organisms have complex genomes. While bacteria and archaea keep all of their genes on a single loop of DNA, humans scatter them across 23 large DNA molecules called chromosomes; chromosome ...

Ecologist Paula Pappalardo hones strategies for identifying these critical ocean organisms Madison Goldberg Plankton such as hyperiids, a group of crustaceans known for their complex eyes, make up ...

Here you will learn about the basics of Gregor Mendel's experiments, which defined the basic patterns of inheritance. We will also examine Morgan's early experiments on linkage and the discovery of ...

The most common organism in the oceans, and possibly on the entire planet, is a family of single-celled marine bacteria called SAR11. These drifting organisms look like tiny jelly beans and have ...
