Genetics/organelles and genes


Hello Thanemozhi,

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!
Kind regards,

Hi Charlotte,

yes, you are correct. A live cell came from another live cell. The  nuclear DNA has the information to create an entire organism as it has the information for the structural and functional component of every cell that makes up that organism. But remember, only the zygote the very first cell of a sexually reproducing organism is the one that has the the total potency. As the cells divide and increase in number, they get recruited to different organs and as they mature, they give up their totipotency to become devoted to one cause. Scientifically, this happens as selective genes are turned off or on. At laboratory level, these switches can be reset to achieve total potency.
