Bioinformatics

“THE MAIN AIM OF THE BIOINFORMATICS IS TO DECODE THE CODE OF LIFE”
Bioinformatics is the application of statistics and computer science to the field of molecular biology. Major research areas of Bioinformatics are:

Sequence Analysis, Genome annotation, Computational evolutionary biology, Analysis of gene expression, Analysis of regulation, Analysis of protein expression, Analysis of mutations in cancer, Comparative genomics, Modeling biological systems and High-throughput image analysis.

Scientific Research Writing

Scientists have discovered polka dot tree frog (Hypsiboas punctatus), the world’s first fluorescent frog in Argentina. The newly discovered amphibian sports a muted palette of greens, reds and yellows under normal light, but in the dark gives off a bright blue and green glow.

What have Scientists discovered?
Scientists found that the polka dot tree frog uses fluorescent molecules totally unlike those found in other animals. Scientists expect to find red fluorescence in these frogs from a pigment called In some insects, proteins bound to biliverdin emit a faint red fluorescence. However, in the polka dot tree frog, biliverdin turned out to be a red herring.

In some insects, proteins bound to biliverdin emit a faint red fluorescence. However, in the polka dot tree frog, biliverdin turned out to be a red herring. In ultraviolet flashlight (or black light), polka dot tree frogs gave off an intense greenish-blue glow instead of a faint red. Three molecules hyloin-L1, hyloin-L2 and hyloin-G1 were responsible for green fluorescence. These molecules contain a ring structure and a chain of hydrocarbons, and are unique among the known fluorescent molecules in animals.
What is Fluorescence? Fluorescence is the ability to absorb light at short wavelengths and re-emit it at longer wavelengths. It is rare in terrestrial animals. Many ocean creatures exhibit fluorescence, including corals, fish, sharks and one species of sea turtle. But, until now, it was unheard of in amphibians. On land, fluorescence was previously known in only parrots and some species of scorpions. But it is still unclear why animals have this ability. Scientists believe that Fluorescence may be shown by animals for the purpose communication, camouflage and mate attraction.
