Front

What does 'antiparallel' mean in the context of DNA strands?

Back

Antiparallel refers to the orientation of the two strands of DNA running in opposite directions.

Front

What phase of the cell cycle is characterized by the reappearance of the nuclear envelope?

Back

Telophase is the phase where the nuclear envelope reappears and the cell prepares for cytokinesis.

Front

What is the primary purpose of DNA replication?

Back

The primary purpose of DNA replication is to create another copy of DNA for the new cell.

Front

Which enzyme is responsible for unwinding the DNA strands during replication?

Back

Helicase is the enzyme that unwinds the DNA strands.

Front

What is the final result of DNA replication?

Back

The final result of DNA replication is two identical copies of DNA.

Front

What is a leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the same direction as the replication fork.

Front

What is a lagging strand in DNA replication?

Back

The lagging strand is synthesized discontinuously in short segments, known as Okazaki fragments, in the opposite direction of the replication fork.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase adds new nucleotides to the growing DNA strand and replaces RNA primers with DNA nucleotides.

Front

What is not involved in the DNA replication process?

Back

Duplication of organelles is not part of the DNA replication process.

Front

What happens during prophase of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
