Comprehensive Study Guide: Growth, Development, and Gene Expression
1. What is the Cell Cycle?


The sequence of growth and division of a cell.
It ensures that cells replicate their DNA and divide properly to form new, functional
daughter cells.
2. Stages of the Cell Cycle:

Interphase – Cell grows, performs normal functions, and replicates DNAr
4. Mitosis Phases:




Prophase: Chromosomes condense, spindle fibers form, and nuclear envelope begins to
break down
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Sister chromatids separate and move to opposite poles
Telophase: Nuclear envelopes reform, and the cell starts to divide
2. Cancer:


Caused by breakdown in cell cycle control in mitosis.
Mutated genes can lead to uncontrolled division
