The mass of human chromosomes, which contain the instructions for life in nearly every cell of our bodies, has been measured with X-rays for the first time in a new study led by UCL researchers.
For the study, published in Chromosome Research, researchers used a powerful X-ray beam at the UK s national synchrotron facility, Diamond Light Source, to determine the number of electrons in a spread of 46 chromosomes which they used to calculate mass.
They found that the chromosomes were about 20 times heavier than the DNA they contained - a much larger mass than previously expected, suggesting there might be missing components yet to be discovered. ....
