Across
- 3. a segment of the chromosome doubles
- 6. line or line segment that separates an angle into two equal parts
- 8. two lines that intersect to create 90 degree angles
- 10. the middle of a line segment, creates two equal parts
- 12. A healthy copy of a gene is introduced into defective cells
- 13. a change in the nucleotide base sequence of a gene or DNA molecule
- 14. types of angles that are adjacent to each other and add up to 180 degrees
Down
- 1. a chromosomal segment breaks off and flips around backwards
- 2. line or line segment that is perpendicular and passes through the midpoint of another line segment
- 4. two lines that never intersect
- 5. mutations that cause death, usually before birth
- 7. two angles that add up to 180 degrees
- 9. two angles that add up to 90 degrees
- 11. the loss of a piece of chromosome due to breakage
