Questions and Answers

What are the major differences between prokaryotic and eukaryotic cells?

Eukaryotic cells have a true nucleus, while prokaryotic cells do not. (correct)

Prokaryotic cells are usually larger in size compared to eukaryotic cells.

Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.

Eukaryotic cells have circular DNA, while prokaryotic cells have linear DNA.

What is the process of transcriptional control at the level of the genome?

Enhancing the process of translation

Methylation of DNA to prevent transcription (correct)

Formation of tRNA molecules

Splicing of exons and introns

What is the function and components of the eukaryotic cell cycle?

Interphase, metaphase, anaphase, telophase; controls protein synthesis

G1, S, G2, M phases; regulates cell growth and division (correct)

G0, G1, G2, M phases; governs energy production in the cell

Prophase, prometaphase, metaphase, anaphase; coordinates cell signaling
