In eukaryotic cells, chromosomes are made up of DNA. DNA can also be found in the chloroplasts and mitochondria, and inside the cytoplasm in the form of plasma. DNA molecules consist of nucleotides ...

Physicists have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and ...

Key building blocks of DNA and RNA can be made from the same raw materials. This finding suggests that instead of one or the other kick-starting life on Earth, both chemicals were involved in the ...
