Where is the nucleolus found
The Nucleolus (the small nucleus)
hey guys it's medicos is perfection
alice let's continue talking about
physiology in the last video we have
talked about the nucleus today let's
talk about the baby nucleus also known
as then nucleolus inside the nucleus
looks darker under the microscope so
let's get started
[Music]
let's reveal what we have discussed in
the previous video the nucleus is the
control center contains DNA inside the
chromosomes and surrounded by a membrane
called nuclear membrane that has pores
the nuclear membrane like any membrane
in your body is a double membrane with
an inter membrane space in between and
it has forced will have selective
exchange for molecules and ions the
outer membrane or the nuclear membrane
is continuous with the rough endoplasmic
reticulum so it has lots of ribosomes on
it the nucleolus which is today's topic
occupies quarter of the nucleus it
appears darker in color and it doesn't
have a membrane what are the functions
assembly of ribosomes and synthesis of
our RNA R stands for ribosomal RNA the
nucleolus enlarged when the cell is
synthesizing proteins because it's more
active then it's like when you're shy
you blush you're more active appear
darker let's have some meta kosis words
of wisdom here the nucleolus is nothing
but a place where there are lots of RNA
and ribosomal proteins that's why we
don't need a nuclear membrane there is
no such thing where is the nucleolus
synthesized or where are the ribosomes
in size they began in the nucleus then
some ribosomes will stay in the nucleus
forming the nucleolus others will go to
the cytoplasm to the outside through the
nuclear pores and they will form the
ribosomes RNA Plus ribosomal proteins
forming ribosomes remember that you can
get all of these notes if you go to
patreon
