Solution
The correct option is B Nucleosomes
The DNA histone thread of chromosome is called chromonema. Basically, the chromonema is made of nucleosome chains. They are formed by complexing of DNA with histone proteins. Nucleosome are oblate structures having a histone octamer of four types of histones molecules (2 of each type)- H2A, H2B, H3 and H4 with their charged parts towards outside and hydrophobic area towards the centre. The charged parts help DNA to coil over nucleosome body. DNA strand between two nucleosomes is called linker DNA. It bears H1 histone. Nucleosomes were observed by Olins and Olins under electron microscope.
