Ecologist Paul Ehrlich gave rivet popper hypothesis to help understand the contribution species richness. He compared each species with rivet in the body of an airplane.
(i)  This hypothesis explains that ecosystem to be an airplane and the species to be the rivets joining all parts together.
(ii)  If every passenger travelling in the airplane start taking rivets home (causing a species to become extinct), initially it may not affect flight safety (proper functioning of ecosystem), but over a period of time the plane becomes weak and dangerous (species become endangered and then extinct.

In prokaryotes, such as, . coll, though they do Core of histone molecules oot have a defined nucleus, the DNA is not scattered Figure 6.4a Nucleosome urroughout the cell. DNA (being negatively charged) is held with some proteins (that have positive charges) in a region termed as 'nucleoid'. The DNA in nucleoid is organised in large loops held by proteins.
  1. In eukaryotes, this organisation is much more complex. There is a set of positively charged, basic proteins called histones. A protein acquires charge fepending upon the abundance of amino acids fesidues with charged side chains. Histones are rich nt the basic amino acid residues lysine and arginine. Both the amino acid residues carry positive charges their side chains. Histones are organised to form
  2. Figure 6.4b EM picture - 'Beads-onunit of eight molecules called histone octamer. The negatively charged DNA is wrapped around the positively charged istone octamer to form a structure called nucleosome (Figure 6.4 a). A pical nucleosome contains 200 bp of DNA helix. Nucleosomes constitute he repeating unit of a structure in nucleus called chromatin, threadke stained (coloured) bodies seen in nucleus. The nucleosomes in hromatin are seen as 'beads-on-string structure when viewed under ectron microscope (EM) (Figure 6.4 b).
  3. Theoretically. how many such beads (nucleosomes) do you imagine be present in a mammalian cell?
  4. The beads-on-string structure in chromatin is packaged to form hromatin fibers that are further coiled and condensed at metaphase stage cell division to form chromosomes. The packaging of chromatin at higher el requires additional set of proteins that collectively are referred to as
