Exploring the Mystery of the Huge Variety of DNA Sizes
Scientists have long been puzzled by the huge variety of sizes of DNA molecules, but new research from an international team of scientists has finally provided an explanation. After studying thousands of different species of organisms, from bacteria to humans, the team discovered that the size of DNA is directly related to the complexity of the organism. The more complex the organism, the larger the DNA molecule. This could explain why humans have so much more DNA than simpler organisms like bacteria. The findings could also help scientists better understand the evolution of organisms and the development of complex life forms.
