Period
During which phase of the cell cycle does DNA replication occur to ensure each new daughter cell receives a complete set of instructions?
A G1 Phase
B S Phase
C G2 Phase
D M Phase
Which of the following describes the final physical division of the cytoplasm, resulting in two distinct individual cells?
A Prophase
B Anaphase
C Cytokinesis
D Telophase
What is the primary biological objective of DNA replication during the cell cycle?
A To convert DNA into messenger RNA for protein synthesis.
B To provide each new daughter cell with an identical set of genetic information.
C To decrease the total amount of genetic material before cytokinesis begins.
D To increase the size of the cell without needing to undergo mitosis.
If the template strand has the sequence TAG, what will be the sequence of the new complementary strand?

DNA Replication Phase
B S Phase
Final Cytoplasm Division
C Cytokinesis
Primary Objective
B Provide each new daughter cell with an identical set of genetic information.
Complementary Sequence (TAG)
A ATC
Connection Challenge
Sample Response: DNA replication must occur first so there are two identical sets of genetic material for division. If skipped, daughter cells would have missing information or half the DNA, preventing survival. Mitosis sorts DNA; it doesn't create it.
