3-D Bird Pictures from Zoological Museum Amsterdam

This site shows how museum collections can benefit from cyberspace. It is a digital specimen case from the Zoological Museum Amsterdam in the Netherlands. The site supplies three-dimensional (3-D) images of 151 avian type specimens (the original examples taxonomists used to describe the species) from around the world. You can rotate or tilt animals. The pages also describe where and when the birds were collected, provide their measurements, and compare them to other specimens. The museum plans to post similar 3-D images of its cache of shells and skulls.

Deciphering the Genetic Code
You know the names Watson and Crick, but how much do you know about Marshall Nirenberg? This National Institutes of Health biochemist figured out that triplets of DNA bases code for specific amino acids in 1961, only 8 years after James Watson and Francis Crick unraveled DNA's helical structure. This new online exhibit chronicles the race to break the code by Nirenberg, who later won the Nobel Prize.

Virtual Genetics Lab
Beginning biology students can run simple genetics experiments, and never have to swat an escaped fruit fly using this site created by Brian White and colleagues of the University of Massachusetts. The software simulates crosses between animals with particular characteristics. As in a real genetics lab, users design their own procedures, deciding how many matings will provide enough evidence to deduce how the trait is passed on. The exercises challenge students to recognize not only simple dominant traits but also more complex types of transmission, such as age and incomplete dominance. Although the problems illustrate real inheritance patterns, they use hypothetical traits, so students can't track down the answers on the Web.
