Question

In following the development of life on Earth, what evolutionary phenomena can we track in the genome that appeared to have significantly escalated the increase in organism complexity? a. Parents producing ample offspring b. Moving from unicellular to multicellular life c. Appearance of non-coding RNA d. Appearance of non-coding DNA e. Appearance of mitochondria

Answer 1

In the evolutionary phenomena of genome the appearance of mitochondria significantly escalated the increase in organisms complexity.  

A prokaryote is a unicellular organism that lacks a membrane bound nucleus, mitochondria or any other membrane bound organelle.The genome of prokaryotic organisms is a circular, double stranded piece of DNA.
