Endosymbiosis And The Origin Of Eukaryotes Flashcards
1
Q
What is the origin of eukaryotes
A
Eukaryotes evolved from Archea. They have similar replication and transcription machinery
2
Q
How did Eukaryotic cells evolve
A
Mitochondria and bacteria share 70S ribosomes and similar RNA sequences. They also both have double membranes and decide via fission.
This suggests endosymbiosis caused the formation of mitochondria in eukaryotes
3
Q
What is primary symbiosis
A
When a eukaryote engulfs a bacterial cell
4
Q
What is secondary endosymbiosis
A
When a eukaryote engulfs another eukaryotic cell
5
Q
What are Asgard Archea
A
The closest relatives of eukaryotes
6
Q
