Front

What is the evidence that mitochondria evolved from prokaryotic cells?

Back

Both mitochondria and bacteria have circular DNA molecules.

Front

What is the significance of DNA analysis in linking suspects to a crime scene?

Back

DNA analysis can identify specific individuals based on their unique genetic profiles.

Front

How do fossil records indicate species changes?

Back

Species changes generally take place over many generations.

Front

What is the primary purpose of restriction enzymes in gel electrophoresis?

Back

They allow the strands of DNA to be cut into various lengths for testing.

Front

What does it imply if species A and B have very similar genes and proteins?

Back

Species A and B share a relatively recent common ancestor.

Front

What is the structure of mitochondria?

Back

Mitochondria have a double membrane structure, consisting of an outer membrane and a highly folded inner membrane.

Front

What role do ribosomes play in cells?

Back

Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.

Front

What is the significance of circular DNA in mitochondria?

Back

Circular DNA suggests a prokaryotic origin, as most eukaryotic cells have linear DNA.

Front

How do environmental changes affect species evolution?

Back

Environmental changes can accelerate or slow down the rate of species evolution.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is used to separate DNA fragments based on their size.
