Comparative Genomics: Prokaryotes vs Eukaryotes

What shape are most prokaryotic chromosomes?

• Triangular

• Linear

• Circular

• Hexagonal

Which type of chromosome configuration do eukaryotes typically have?

• Single and circular

• Single and linear

• Multiple and circular

• Multiple and linear

Which cellular structure contains additional genetic material in eukaryotes?

• Golgi apparatus

• Nucleus

• Mitochondria

• Ribosomes

What are plasmids commonly found in?

• Both

• Prokaryotes

• Eukaryotes

• Neither

What role do mitochondria play in eukaryotic genetics?

• They are involved in lipid synthesis

• They contain no genetic material

• They house additional genes

• They are solely energy producers

Approximately how many genes are found in a typical eukaryotic organism?

• Thousands

• Millions

• Hundreds

• Tens of thousands

What does the presence of non-coding DNA in eukaryotes suggest?

• Potential regulatory functions

• Higher mutation rates

• Lack of genetic complexity

• Smaller genome size

What is the primary function of histones in eukaryotic cells?

• Protein synthesis

• DNA packaging

• Transcription regulation

• DNA replication

What is an operon?

• A sequence of DNA that codes for histones

• A cluster of genes under a common promoter

• A type of organelle

• A method of DNA replication

Which organisms are known to have operons?

• Only prokaryotes

• Only eukaryotes

• Neither prokaryotes nor eukaryotes

• Mostly prokaryotes, rarely in eukaryotes
