For the question "4. A previously undiscovered single celled organism was found living at a great depth on the ocean floor. Its nucleus contains only a single, linear chromosome consisting of 7x 106 nucleotide pairs of DNA coalesced with three types of histone-like proteins. The analysis of individual nucleosomes revealed that each unit contained one copy of each protein and that the short linker DNA had no protein bound to it If the entire chromosome consists of nucleosomes (discounting any linker DNA), how many are there and how many total proteins are needed to form them?" I was given the answer below: As per question the chromosome contains 7×106 base pairs of DNA, The number of nucleosomes, each containing 7 × 102 base pairs, is equal to : 7 × 106 /7 × 102 = 104 nucleosomes I was wondering how they knew each nucleosome contains 7 × 102 base pairs?
