Unit 6 Notes: Cancer & Mutations

3. (1) Mutations Mutation: Effects: Change in DNA sequence (gene)
Changes protein produced
Effects:
…All cells with that gene
…Mitosis
…Meiosis

5. (2) Mutations & Mitosis Involves Somatic Cells
Possible Results to Cells:
Damage structure
Cannot function
….Cancer?

6. (3) Mutations & Meiosis Involves Germ Cells Possible Results to Cells:
Affect any zygote produced from mutated gamete
If zygote (w/mutation) develops:
Every cell will contain mutation
Germ cells will contain mutation  Next Generation

7. (4) Cancer Disease Spreads through blood + lymph.
Abnormal cells divide and grow w/o control
Abnormal cells invade other tissues
Spreads through blood + lymph.
More than 100 known types, named by origin.
Tumor:
Not always cancerous.
Result of uncontrolled cell growth
Mass of tissue
