Genetic Complexity Of The Humble Water Flea
The genetic complexity of the humble water flea is more complex than in a human being.Scientists report that the one millimeter-long creature carries more genes than other forms of animals known. To say the least, a total count of around 31,000 genes are found packed into its DNA. In contrast, human beings are known to have only around 23,000 genes.
The common water flea, Daphnia pulex, was the first crustacean to undergo a blueprint recording displaying the sequence of various chemical sequences that make up genetic code, or genome. The Daphnia appears to be just ordinary, with a transparent body, jointed limbs, having compound eyes and a simple nervous and circulatory system. But comparatively its genome is found to be unusually large but full of surprises.
More than one third of Daphnia’s genes are not documented in any other living organism – that is to reflect, “they are entirely new to science,” said Dr Don Gilbert, one of the researchers from Indiana University at Bloomington in the United States.
Scientists from the University of Edinburgh were also involved in the project.
