Answer:
b. Eukaryotic cell structure
Explanation:
LUCA - the last universal common ancestor with its structure looked more like bacteria: small, single-celled organism with a ring-shaped coil of DNA which floated freely within the cell (no nucleus like eukaryotic cell). It is estimated LUCA lived 3.5 to 3.8 billion years ago. The genetic code of LUCA was based on DNA and it did the functions such as transcription and translation.

Sickle-cell anemia is a disease that is caused by a mutation in the beta-globin chain of the protein, hemoglobin.
<h3>What is sickle cell anemia?</h3>
Sickle cell anemia is a disease caused by a mutation in the beta-globin chain of the protein hemoglobin.
The mutation occurs on the beta-hemoglobin gene found on chromosome 11.
In sickle cell anemia, the red blood cells have as sickle shape and are unable to transport oxygen effectively in the body.
Therefore, sickle-cell anemia is a disease that is caused by a mutation in the beta-globin chain of the protein, hemoglobin.
