Great video but perhaps clarify a little more at the end, with the large and small subunit entry into the nucleus. You said they join up, how exactly? Everything described before that was done beautifully but I would like a little extrra info on the final production of the completed RNA. Cheers!
This Video is so AWESOME!!! I always wondered what was up with Ribosomal RNA? Like why not just have a 100% Protein-based Ribosomes? The origin of Ribosomes and their influence on life as we noticed has always fascinated me and i Cannot wait for the many scientific discoveries that will be made in the future.
Hi, it says in my book: The nucleolus is responsible for Ribosomal (rRNA) synthesis and ribosomal assembly. It contains 3 morphological distinct zones: -Granular Zone : Found at the periphery; contains ribosomal precursor in various stages of assembly. -Fibrillar Zone : centrally located ;contains ribonucleic protein fibrils. -Fibrillar center : Contains the DNA that is not being transcribed. I don't understand the zones, and the importance of each one. Can someone just elaborate and explain. And what is meant by Ribonuclear protein fibrils? Great video btw :)
So its three centers (1) Granular Center (2) Dense Fibrillar Center and (3) Fibrillar Center Fibrillar Center - contains Inactive DNA, this could mean DNA we no longer use anymore, So for example in the DNA for embryo development or the in females there is an inactive X chromosome. if DNA is INACTIVE hence it is NOT TRANSCRIBED. Dense Fibrillar Center - surronds the the fibrillar centers and this contains the pre-RNA synthetic site Granular Center - Is the majority region of Nucleolus assemby of ribosomal subunit assembly.
Great video. Could you please explain if Nucleolus is only condensed DNA that functions to produce rRNA only, or it also contains DNA for other transcription?
the voice is so monotonous,& dull,,, lack of enthusiasm.voice of muscle physiology vedio is perfect. i hope u understand the basic fact that if voice is dull evrybody will going to sleep in class. btw vedio is so informative .

I was taught that the nucleolus was an organelle. Can you please clarify? Thank you
It is a sub-organelle
nucleolus is in the nucleus which is an organelle
it looks like whoever discovered the nucleus was running out of names. Nucleoli, nucleolus, and nucleus...and no clear explanation of what is what.

I also don't understand
Thank you very much
Thank u soo much sir
Fabulous
Nuclioli positive (1+)enth treatment cheyyum
is the ribosaml dna an indivduial dna not counted with the normal 46 chromosome?.. or its part of 1 chromosome or what
Clear and functional. Thank you very much for explanation.
thank u so much! it really enlightened me🌸
I can't pay attention to this wth
Would you pls tell me which app/software are you using?? That is really good.. This video is also good and helpful.
great explanation.
Super vid! One more subscriber! And earned in full :)
thank you so much for this video!
Neat illustrations!
Great vid, very clear, thank you. May I ask what package you used to present it, thank you?
Thnk you very much
awesome!!
حد يترجمه🙂💔
i LOOOOOVE this video!!! Step by step explained in a clear and systematic way! Great work!
