Enzymes are Proteins

Enzymes are proteins that speed up the reactions by acting as catalysts. They increase the rate of reaction without being consumed or permanently altered by themselves. In Greek enzymes are divided into sections “En” which means “in” and second part is “zyme” means living. The study of enzymes is known as...

Electrophoresis gel with annotation

Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA. A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black
band appears in a particular lane that base is present. By reading off the order of bands across the four lanes the...

Automated DNA sequencing output

The output from an automated DNA sequencing robot used by the Human Genome Project to determine the complete human DNA sequence. Each peak shows the presence of a particular base. The sequence of bases in a given stretch of DNA can therefore be read from the order of the peaks along the trace. The sequences of...
