10 Questions
What are the major differences between prokaryotic and eukaryotic cells?
Eukaryotic cells have a true nucleus, while prokaryotic cells do not.
What is the process of transcriptional control at the level of the genome?
Methylation of DNA to prevent transcription
What is the function and components of the eukaryotic cell cycle?
G1, S, G2, M phases; regulates cell growth and division
How do proteins interact and what biochemical changes take place that facilitate signal transduction?
Proteins interact through phosphorylation and dephosphorylation; biochemical changes include activation of second messengers.
How is the role of programmed cell death (apoptosis) in development of multicellular organisms?
It eliminates unwanted or damaged cells during development and maintains tissue homeostasis.
Which process involves DNA isolation, digestion (cleavage) and ligation?
DNA cloning (recombinant DNA technology)
What drives genome complexity?
Transcriptional control at the level of the genome
What is the role of programmed cell death (apoptosis) in development of multicellular organisms?
It plays a role in development of multicellular organisms
What is the function of the mitogen activated protein kinase (MAPK) cascade?
Facilitates signal transduction
What are the major differences between prokaryotic and eukaryotic cells?
Presence of membrane-bound organelles in eukaryotic cells
