Across
- 3. abnormal cell growth
- 5. A cancer-causing substance that work by interacting with a cell's DNA and inducing genetic mutations.
- 7. A chart that shows the size, number and shape of all the chromosomes in an organism. Scientist use the size, centromere position, and banding pattern to match the chromosomes.
- 8. Deoxyribonucleic Acid. It provides instructions or blue prints to make proteins.
- 9. A subunit of DNA that is made of one phosphate, a sugar molecule and one nitrogen base.
Down
- 1. A permanent change in the DNA sequence. These changes can either cause harm, have no effect, or occasionally improve an organism's chance of survival.
- 2. A chemical or physical agent that interacts with DNA and causes a mutation.
- 4. Rod-shaped structures composed of DNA and protein that function to organize the genetic material so that it can be properly passed on during cell division.
- 6. the study of environmental influence on gene expression that occurs without a DNA change
