How much do you weigh No, it’s not your weight (we’re not judging here). Chromosomes, An X-shaped bundle of genetic instructions that make you You are??
If you don’t know it directly, scientists will cover it. Using one of the UK’s most powerful X-ray beams, a team of researchers recently measured the mass of 46 human chromosomes.
The result was amazing. Each chromosome was about 20 times heavier than the chromosome. DNA According to their study, published in the journal on March 31, they contained-much larger mass than researchers expected. Chromosome research..
Relation: Is the Y chromosome dying?
“Our measurements suggest that each cell weighs 242 picograms (one trillionth of a gram) of 46 chromosomes. Said in a statement“This is heavier than we would expect and, when replicated, shows an unexplained excess mass of chromosomes.”
Normally, each human cell contains 23 pairs of chromosomes. Within each chromosome is a single DNA molecule and a large number of proteins that perform different functions. For example, it can perform a variety of functions, such as compressing a 6.5-foot (2-meter) long DNA strand into small bundles that fit into individual cells.
The Human Genome Project, run by the U.S. government, unveiled the masses of DNA molecules, among other things, but the weight of the chromosomes that house these molecules remained a mystery. More insights may be gained about.
To calculate the mass of a standard set of 46 human chromosomes, the authors of the study used a technique called X-ray tycography. X-ray Beam of the British Diamond Light Source Science Center in Oxfordshire. Using this model, researchers can calculate the exact number of electrons on each chromosome, and researchers can estimate the total mass of chromosomes.
The fact that chromosomes weigh 20 times more than DNA has puzzled the team. So far, there is no good explanation for this “excessive” mass, but further research may reveal the secrets hidden under X.
