found in most eukaryotic cells
...
The genetic information, which
contains the information for the
structure and function of the
organism
...
Chromosomes
Itʼs the long strands of
coiled-up DNA and proteins
...
Gene expression
Is the process by which
the information in a
gene is “decoded” by
various cell molecules to
produce a functional
gene product, such as a
protein molecule
...
The Nuclear
Envelope
Itʼs a double membrane
of the nucleus that
encloses the genetic
material
...
The outer membrane is
continuous with the rough
endoplasmic reticulum
...
Nuclear pores
It help to regulate the
exchange of materials
(such as RNA and
proteins) between the
nucleus and the
cytoplasm
...
Function
The nucleolus is mainly
involved in the assembly
of ribosomes
...
