• The duplication of the entire genome during cell division
The movement of genetic material between different cells or organisms
• The permanent alteration of the DNA sequence within a gene

Which of the following is the best example of cell differentiation? (1 point)
• A bacterial cell dividing into two identical daughter cells
• A muscle cell repairing itself after injury
• A stem cell developing into a nerve cell
• A cancer cell undergoing uncontrolled division

Which of the following is the correct order of the steps of the cell cycle? (1 point)
G1, S, G2, M
• G2, G2, S, M
• G2, G1, S, M
S, G1, G2, M

Which of the following is the best explanation of telophase during mitosis? (1 point)
Nuclear envelopes reform around the chromosomes, and the chromosomes begin to decondense.
• Sister chromatids separate and move to opposite poles of the cell
• Chromosomes condense and become visible, and the nuclear envelope breaks down.
• Chromosomes align at the cell's equator, and spindle fibers attach to centromeres.

Answer 1

1) Gene expression: The process by which genetic information is read and becomes differentiated.
2) Cell differentiation: A stem cell developing into a nerve cell.
3) Cell cycle order: G1, S, G2, M.
4) Telophase: Nuclear envelopes reform around the chromosomes, and the chromosomes begin to decondense.
