3. INTRODUCTION
Eukaryotes are organisms whose
cells contain a nucleus and other
membrane-bound organelles.
There is a wide range of eukaryotic
organisms, including all animals,
plants, fungi, and protists, as well as
most algae.
Eukaryotes may be either single-
celled or multicellular.

5. GENETIC ORGANISATION IN EUKARYOTES
In eukaryotes, the major part of DNA is found
in the chromosomes, which themselves are
present within the nucleus.
The eukaryotic cell membrane has pores and
is continuous with the endoplasmic reticulum.
The eukaryotes have varied number of
chromosomes which is fixed for a biological
species.
During cell division the physical characteristics
of chromosomes vary
6. Histone :- it provides structural support
to chromosome.
Chromatin :- mixture of DNA and
PROTEIN that from chromosome found
in the cells of organisms.
Bead nucleosome :- A section of DNA
wrapped around a core of protein
