PROKARYOTES VS. EUKARYOTES
structures is found in eukaryotic cells but never in prokaryotic cells?
Which of the following structures is found in eukaryotic cells but never in prokaryotic cells?
NUCLEUS Correct! Prokaryotes lack a membrane-bound nucleus and store their DNA in a nucleoid region, whereas eukaryotes house their DNA inside a true membrane-bound nucleus.
who discovered cells

cell
what instrument is used to see tiny objects
microscope
What is the control center of the cell?
nucleus
.Which of the following groups consists exclusively of prokaryotic organisms?
Both Bacteria and Archaea are domains of single-celled organisms that lack a membrane-bound nucleus and internal membrane-bound organelles
what did robert hooke observes under microscope
cork cells
what it the jelly like substances inside a celll
cytoplasma
what part of the microscope do you look through
eyepiece
Which organelle produces energy for the cell?
Mitochondria
Why are prokaryotic cells generally able to couple transcription and translation simultaneously, whereas eukaryotic cells cannot?
A.
Correct! Because prokaryotes have no nucleus to separate transcription (in the nucleus) from translation (in the cytoplasm), ribosomes can begin translating mRNA while RNA polymerase is still transcribing it.
