Step 1: Understanding prokaryotic cell structure.
Prokaryotic cells lack membrane-bound organelles. Their genetic material is not enclosed within a nuclear membrane.
Step 2: Effect on transcription and translation.
Because there is no nucleus, transcription and translation occur simultaneously in the cytoplasm.
Step 3: Eliminating incorrect options.
Chromosome, ATP and ribosomes are present in prokaryotes, but the nucleus is absent.
