How much does DNA weigh?

The weight of DNA can vary depending on its length and structure, but on average, a single base pair of DNA weighs approximately 650 daltons. To give a broader context, the total weight of DNA in a human cell is roughly 6 picograms. Therefore, the total weight of all the DNA in an average human body, containing about 37 trillion cells, is estimated to be around 0.1 grams.
