DNA Replication and Cell Cycle Review

Front

What are the components of DNA?

Back

DNA consists of alternating phosphate groups and deoxyribose molecules.

Front

What does the 'S' in S-phase stand for?

Back

The 'S' in S-phase stands for synthesis.

Front

What does synthesis mean in the context of the cell cycle?

Back

Synthesis means to make.

Front

What color is commonly used to represent DNA replication?

Back

ORANGE.

Front

During which phase of the cell cycle is DNA replicated?

Back

DNA is replicated during S-phase.

Front

What happens during anaphase of mitosis?

Back

During anaphase, sister chromatids are separated and pulled to opposite sides of the cell.

Front

How many chromosomes are present in a human somatic cell?

Back

A human somatic cell typically contains 46 chromosomes.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for cell growth, DNA replication, and cell division, ensuring proper development and maintenance of organisms.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).
