Only
around 2% of the human genome actually codes for proteins. The rest is
known as non-coding DNA, and much of it seems to be the remnants of
evolutionarily defunct genes and viruses that hijacked a ride on our
chromosomes. Biologists have long puzzled over this seemingly redundant
DNA and many hypothesis have been put forward for why it exists.
A study published this week suggests that contrary
to previous hypothesis, non-coding DNA is not necessary for complex
life. Researchers have sequenced the genome of genome of the carnivorous
plant Utricularia gibba and found that more than 97% of the genome
consists of coding DNA and DNA that controls these genes. Unlike humans
and most other examined genomes, U. gibba seems to have the ability to
delete non-coding "junk" DNA.
