## Mass of dna per cell ### Here comes the science bit and a few key points to remember

Exact M.W. of ssDNA (e.g., Oligonucleotides): M.W. = (An x ) + (Tn x ) + (Cn x ) + (Gn x ) + ª An, Tn, Cn, and Gn are the number of each respective nucleotide within the polynucleotide. ªAddition of "" to the M.W. takes into account the 5' monophosphate left by most restriction enzymes. The normal haploid genome is x 10^9 bp. At g/mole-bp and Avogadro's number of x 10^23 bp/mole, I get x 10^ g/haploid genome, or picogram per genome. The diploid genome then is about 7 picograms. We have 3 billion base pairs per cell - which gives us about pico-grams of DNA per cell. (6e) Then all we need is the number of cells -- as was mentioned above, estimates vary widely, but its between 1 and 10 trillion cells (1e12 to 10e. ### Biodiversity, classification, conservation

Prokaryote's genetic material, better known as DNA, is not in a cellular structure called the nucleus. Eukaryotic cells do have nuclei. Generally the masses vary between different types of bacterium. A typical mass of a bacterium would be about 10 −12 g or one picogram (pm). If the DNA is single-stranded, then multiply the number of bases by the average mass of a single base ( g/mol) to get the approximate mass of the whole molecule. Better still, if you know the. 5/09/ · That is nuclear DNA. If we wanted to include mitochondrial DNA: We have around ~16, base pairs per mt genome * daltons per base pair * ~ mtDNA molecules per cell * x grams per dalton * x10 13 cells = ~ grams. Not a huge difference. And of course this is just human cells. ### This information may come in useful when doing the following applications:

Not a huge difference. And of course this is just human cells. 17/09/ · The average weight of a single DNA base pair (bp) is daltons. This can also be written as g/mol (= molar mass) This is the same as saying that one mole of a bp weighs g. DNA is about atomic mass units per base pair. We have about three billion base pairs per cell and about trillion cells. That means we have about 10 26 base pairs of DNA or about grams. level 2.
