question 32 of 32
which of the following is not a trait shared by chloroplasts and prokaryotic cells?
○ the size of their ribosomes
○ their mechanism of replication
○ the presence of a nucleus
○ the shape of their dna molecule

Explanation:

Chloroplasts (organelles) and prokaryotic cells both lack a nucleus. Ribosomes of chloroplasts and prokaryotes are similar in size (70S), their DNA is circular, and they replicate independently (binary fission-like for chloroplasts, binary fission for prokaryotes). The presence of a nucleus is exclusive to eukaryotic cells, so it is not a shared trait.

Answer:

the presence of a nucleus
