DNA and Cell Cycle

What is the structure of DNA?

• The structure of DNA is a single strand.

• The structure of DNA is a triple helix.

• The structure of DNA is a square.

• The structure of DNA is a double helix.

What is the function of DNA?

• The function of DNA is to store genetic information.

• The function of DNA is to regulate cellular processes.

• The function of DNA is to protect the cell from external threats.

• The function of DNA is to produce energy for the cell.

What is DNA replication?

• DNA replication is the process of copying a double-stranded DNA molecule to produce two identical DNA molecules.

• DNA replication is the process of creating a single-stranded RNA molecule from a double-stranded DNA molecule.

• DNA replication is the process of creating a completely new DNA molecule that is different from the original.

• DNA replication is the process of breaking down a double-stranded DNA molecule into two single-stranded DNA molecules.

What are the stages of the cell cycle?

• interphase, mitosis, and cytokinesis

• telophase, anaphase, and prophase

• prophase, metaphase, and anaphase

• cytokinesis, interphase, and telophase

How does DNA determine an organism's traits?

• DNA determines an organism's traits by controlling the environment it lives in

• An organism's traits are determined by its diet and exercise habits

• DNA contains the genetic information that codes for proteins, which determine an organism's traits.

• An organism's traits are randomly assigned at birth and have no relation to DNA

What is a gene?

• A gene is a segment of DNA that codes for a specific protein.

• A gene is a type of cell.

• A gene is a structure within the cell nucleus.
