5 Virtual Labs and More - The Genetic Science Center at the Univeristy of UTAH - UNIVERSITY OF UTAH

This is another wonderful find. The Genetic Science Center at the University of Utah. It has 5 virtual labs of very high quality! And a whole bunch of interactive resources. I'll do my best diagram them below with screen shots! :) Enjoy!

Link to main site: http://learn.genetics.utah.edu/

As I mentioned, inside you'll find sections devoted to each area of genetics with animations, 3D visualizations, interactive hands on learning tutorials and labs! So go explore this site to its fullest!

Alright now for the quick links to the... 5 Virtual Labs!

PCR VIRTUAL LAB

PCR is a relatively simple and inexpensive tool that you can use to focus in on a segment of DNA and copy it billions of times over. PCR is used every day to diagnose diseases, identify bacteria and viruses, match criminals to crime scenes, and in many other ways. Step up to the virtual lab bench and see how it works!

DNA EXTRACTION VIRTUAL LAB

DNA is extracted from human cells for a variety of reasons. With a pure sample of DNA you can test a newborn for a genetic disease, analyze forensic evidence, or study a gene involved in cancer. Try this virtual laboratory to perform a cheek swab and extract DNA from human cells.

GEL ELECTROPHORESIS VIRTUAL LAB

Have you ever wondered how scientists work with tiny molecules that they can't see? Here's your chance to try it yourself! Sort and measure DNA strands by running your own gel electrophoresis experiment. Click Here!











DNA MICROARRAY VIRTUAL LAB
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment! Here you will use a DNA microarray to investigate the differences between a healthy cell and a cancer cell. Click Here!

Hands On LEARNING:


Understanding the Vector ToolBox
Genes are made of DNA. Successful gene delivery requires an efficient way to get the DNA into cells and to make it work. Scientists refer to these DNA delivery "vehicles" as vectors. Click Here


BUILD A DNA MOLECULE
DNA bases characteristically pair G with C, and A with T. Use these pairing rules and the nucleotides below to build a DNA strand containing five base pairs. Click Here











TRANSCRIBE A DNA SEQUENCE AND TRANSLATE IT INTO A PROTEIN

The DNA that makes up the human genome can be subdivided into information bytes called genes. Each gene encodes a unique protein that performs a specialized function in the cell. The human genome contains more than 25,000 genes. Cells use the two-step process of transcription and translation to read each gene and produce the string of amino acids that makes up a protein. The basic rules for translating a gene into a protein are laid out in the Universal Genetic Code. To see how this works, look over the diagram at the right. Then try it yourself in the activity below! Click Here


MAKE A KARYOTYPE
A karyotype is an organized profile of a person's chromosomes. In a karyotype, chromosomes are arranged and numbered by size, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder. To make a karyotype, scientists take a picture of someone's chromosomes, cut them out and match them up using size, banding pattern and centromere position as guides.
