Biology Cell Cycle and Cancer
Exam 2025 Questions and Answers
what cell division can do - ANSWER✔✔-can be a form of reproduction
used to repair damaged cells
for growth
why cells divide - ANSWER✔✔-DNA overload
trouble moving nutrients and wastes across cell membrane less efficient
chromatin - ANSWER✔✔-unorganized DNA found in non dividing cells and has a
single or double copy of DNA
chromosomes - ANSWER✔✔-organized DNA found in dividing cells that has a double
copy of DNA
chromatids - ANSWER✔✔-organized DNA found in dividing cells that have a single
copy of DNA
, Cell cycle - ANSWER✔✔-1. cell grows
2. prepares for division
3. divides to form 2 daughter cells
4. begins cycle all over again
Interphase - ANSWER✔✔-Gap 1, Synthesis, Gap 2; longest phase and most cells are in
this phase
Gap 1 - ANSWER✔✔-Phase when cell grows and performs normal function
Synthesis - ANSWER✔✔-Phase when DNA replicates
Gap 2 - ANSWER✔✔-cell prepares to divide
M Phase - ANSWER✔✔-Mitosis and Cytokinesis; part when cell divides
Mitosis - ANSWER✔✔-Prophase, Metaphase, Anaphase, Telophase
Prophase - ANSWER✔✔-Chromatin coils to form chromosomes
nuclear envelope and nucleolus break down
spindle forms
centrioles move to opposite ends of the cell
metaphase - ANSWER✔✔-spindle moves chromosomes to middle of cell
