Ribosomes are assembled in the cytoplasm, not the nucleolus. The nucleolus produces ribosomal subunits, but these must be exported into the cytoplasm through nuclear pores in order to be assembled in the cytoplasm into fully functioning ribosomes.
Christie Lovat yes this is what I read in my textbook as well. Is he wrong or are there different circumstances in which some ribosomes are manufactured inside the nucleus? Please answer
I just looked this up on Google - "The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell." So I think he got ribosomal subunits confused with ribosomes.
" The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum."
Very well explained, it would have been good though if you had explained what are the substances and molecules that interact with the nucleus such as CO2, Oxygen among other bunch of stuff that i'm actually looking for.
BlackhawkX02 CO2 and Oxygen, do not interact with the nucleus. Doing so will oxidize the DNA. The only reason it’s safe in the body is because Oxygen and CO2 are either being carried by globular proteins or ions (only CO2 which is Bicarbonate). When it enters the cell it will be transported in vesicles and used for whatever is required.
Looking at the nucleus, you can see it is enclosed by a membrane . We say that the nucleus is compartmentalized because it is separated from the other organelles by the membranes.
The continual verbal mishaps made this video one of the harder ones to watch from Khan Academy. I homeschool and use KA on a daily basis, but this particular video leans towards a poorer quality because of the man speaking. Please replace this with a more eloquent lecturer.

@@ShinySephiroth1 Thank you!

Ribosomes are mostly constructed in the nucleus but the final stages of this assembly occur in the cytoplasm.
" The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum."
Thank you! It helped me a lot!
sweet,simple and effective explanation. Great! Thanks for helping me in my class presentation,my topic was nucleus and its functions. :)
that was amazing thanks so much

Explained perfectly! Thank you!
great video, Thank you
Thank you
Very well explained. Thanks a ton!
the explanation was quite detailed!
that was amazing!! Thanks so much!!!
very good video, thanks!
floora khadija p
push the button
nice explanation.
Great video, very clear, thank you
khan academy is the
best
Great !!
Very Good
Thanks great
Nucleus is the factory of protein
Thankkkkk uuuuu
OM NAMAHSHIVAYA
thanks
Thanks, amazing explain but what about chromatin network?
amazing
Can you please make a video on Cytoplasm?
I wonder if and how a spike protein can enter the nucleus to create more spike proteins etc
what does non-compartmentlized mean? 0:57
Guys help!🙂

thank you ❤❤
Great
what is function GIT?
Can a nucleus movement occur in cell....?
nope, proteins anchor the nucleus in its place
Good
What would YOU buy for the nucleolus’ birthday - money is not an issue! What could make my nucleoli genuinely happy?
This was very helpful! Although, why did he make so many mistakes while talking?
because he's a human?
and human errors happen!
why does your voice sound like Ian Somerhalder's voice?? im so weirded out lol i see damon salvatore teaching me citology
Lol yeah I just watched vampire diaries and I was just about to comment the same thing
Thought the same they sound very similar although Ian has a more deep accent!
fuck everyone else, i respect you Khan Academy!
Good video man (Y)
so its basically a little pacman generator in a pacman maze
what is RNA ?
Ribo Nucleic Acid
Plz reply
Am I seeing things, or is the nucleus wiggling on the inside?
WHy do I hear Joe Rogan the whole video lol
not much explanation
Not satisfied. Please describe it in more details

Not everyone can be perfect like you, Jennifer.
Damn u a hater 😂
She is not perfect no one is but I agree
of course she isn't. she "homeschools" her kids.
smh read the description guys and don't complain
Seek Christ Jesus YHVH God :)
Allahu akbar
not to gooooood!
Not good
Thank You
Thanks
