This video is about the Nucleosome Model proposed by P. Outdet. In chromosomal organization the DNA is associated with Histone proteins .The nucleosome is the repeating unit that consists of Core particles of octamer of Histones- H2a, H2b, H3 and H4, and 140bp DNA coiled around it. The 60bp DNA is linked from outside to H1 Histone protein through loose bond. This is universally accepted model that shows the lowest level coiling of DNA and it appears as “String On Beads”.

This video lecture is about the nervous system of Prawn. Prawn has well developed nervous system having supraoesophageal ganglia as brain, ventral thoracic mass and double origin ventral Nerve Cord as Central Nervous System. Nerves arise from the brain, ventral thoracic mass and ventral nerve cord and supply to various appendages and other body parts…
