What are 3 pieces of evidence for the endosymbiotic theory?

Numerous lines of evidence exist, including that mitochondria and chloroplasts have their own circular DNA (prokaryotes also have circular DNA), mitochondria and chloroplasts have a double membrane (the inner membrane would have initially been the ingested prokaryote’s single membrane, and the outer membrane initially …

What is Lynn Margulis endosymbiotic theory?

She proposes that three organelles: mitochondria, plastids, and basal bodies, which are all parts of eukaryotic cells, were once free-living cells that took residence inside primitive eukaryotic cells. This process Margulis called endosymbiosis.

Is the endosymbiotic theory true?

These theories were initially dismissed on the assumption that they did not contain DNA. This was proven false in the 1960s, leading Hans Ris to resurrect the idea. Endosymbiosis is a debate that has been widely accepted in the molecular biology world.

Is there evidence for endosymbiotic theory of mitochondria?

The evidence that is typically offered for endosymbiotic theory includes the following: Mitochondria possess a circular genome (lacking in introns and independent from the nuclear DNA) in which transcription is coupled to translation, characteristic of bacterial DNA. There are also some other notable similarities.

How is the endosymbiotic theory related to prokaryotic evolution?

The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes. Available data indicate that the mitochondrial endosymbiosis initiated the evolution of the eukaryotic cell, as suggested by Margulis.

The theory of how mitochondria, chloroplasts and other membrane-bound organelles in eukaryotic cell likely arose from a symbiosis between aerobic prokaryotes and host anaerobic eukaryotic ancestors.

How did Lynn Margulis come up with the endosymbiotic theory?

Endosymbiotic Theory History First proposed by Boston University biologist Lynn Margulis in the late 1960s, the Endosymbiont Theory proposed that the main organelles of the eukaryotic cell were actually primitive prokaryotic cells that had been engulfed by a different, bigger prokaryotic cell .
