DNA and Cell Cycle Test Review

Front

What is the process of DNA Replication?

Back

DNA Replication is the process by which a cell makes an identical copy of its DNA, ensuring that each new cell receives a complete set of genetic information.

Front

What phase of the cell cycle is characterized by the separation of sister chromatids?

Back

Anaphase is the phase of the cell cycle where sister chromatids are pulled apart to opposite poles of the cell.

Front

Which nitrogenous base pairs with Guanine in DNA?

Back

Cytosine pairs with Guanine in DNA.

Front

What is a characteristic feature of viral samples?

Back

Viral samples often contain nucleic acids (DNA or RNA) surrounded by a protein coat, and they cannot replicate independently without a host cell.

Front

What type of cells form a cleavage furrow during cytokinesis?

Back

Animal cells form a cleavage furrow during cytokinesis, which is the process of dividing the cytoplasm to form two daughter cells.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase (Synthesis phase), DNA is replicated, resulting in the duplication of chromosomes.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is the first gap phase where the cell grows, synthesizes proteins, and prepares for DNA replication.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes with half the number of chromosomes.

Front

What is the function of the spindle apparatus during cell division?

Back

The spindle apparatus helps separate chromosomes during mitosis and meiosis by attaching to the centromeres and pulling them apart.
