Question

The last universal common ancestor (LUCA) was
most likely a blank, containing a cytoplasm surrounded by a lipid bilayer membrane, but with no nucleus.

Answer 1

Answer:

Prokaryotic

Explanation:

That one cell is called the Last Universal Common Ancestor, or LUCA. It probably existed around 3.5 billion years ago. LUCA was one of the earliest prokaryotic cells. It would have lacked a nucleus and other membrane-bound organelles.

Answer 2

Based on the characteristics, the LUCA or the last universal common ancestor would most probably be a prokaryote.

What is a LUCA?

It has been estimated that that last universal common ancestor or the LUCA originated about 3.5 billion years ago during the Archean Eon, which afterwards gave rise to all the cellular forms on the planet. It is considered that the organism possibly possessed both ribosomes and cell membrane and utilized DNA for storing information.

Apart from this, this organism also possessed proteins for catalyzing chemical reactions and RNA from transferring information. However, with the absence of nucleus and other membrane bound organelles, LUCA would possibly be a prokaryote.

Thus, LUCA would possibly be a prokaryote.
