Hello,

I was wondering if you could answer the following question:
How do the cell organelles (apart from the nucleus and mitochondria) found in a human form? Does the nuclear DNA encode for the formation of these organelles (eg Golgi apparatus, Microtubules, cilia etc) in an individual?
Thanking you in advance for your time and help!
