Quiz - Eukaryotic Cell - Organelles

What is the defining characteristic of a eukaryotic cell?

• Membrane-bound organelles
• Free-floating ribosomes
• A single circular chromosome
• A cell wall

Answer explanation

Eukaryotic cells are defined by having membrane-bound organelles such as the nucleus.

What form does genetic information typically take in most cells?

• RNA
• DNA
• Proteins
• Lipids

Answer explanation

DNA is the primary molecule for storing genetic information in cells.

Where is the genetic information located in a eukaryotic cell?

• Cytoplasm
• Ribosomes
• Nucleus
• Mitochondria

Answer explanation

In eukaryotic cells, DNA is stored in the nucleus.

What cellular structure is connected to the nuclear membrane via pores?

• Golgi apparatus
• Vacuole
• Lysosome
• Endoplasmic reticulum

Answer explanation

The endoplasmic reticulum is physically connected to the nuclear envelope through pores.

Where does the transcription of DNA into mRNA take place?

• Nucleus
• Ribosomes
• Mitochondria
• Golgi apparatus

Answer explanation

Transcription takes place in the nucleus where DNA is located.

What is the defining characteristic of a eukaryotic cell?

• Membrane-bound organelles
• Free-floating ribosomes
• A single circular chromosome
• A cell wall

Answer explanation

Eukaryotic cells have membrane-bound organelles, unlike prokaryotic cells.

What form does genetic information typically take in most cells?

• RNA
• DNA
• Proteins
• Lipids

Answer explanation

DNA stores genetic information in the majority of living organisms.

Where is the genetic information located in a eukaryotic cell?

• Cytoplasm
• Ribosomes
• Nucleus
• Mitochondria

Answer explanation

The nucleus houses DNA in eukaryotic cells.

What cellular structure is connected to the nuclear membrane via pores?

• Golgi apparatus
• Vacuole
• Lysosome
• Endoplasmic reticulum

Answer explanation

The endoplasmic reticulum is directly connected to the nuclear membrane.

Where does the transcription of DNA into mRNA take place?

• Nucleus
• Ribosomes
• Mitochondria
• Golgi apparatus

Answer explanation

Transcription of DNA to mRNA occurs in the nucleus.
