Across
- 5. traits controlled by two or more genes
- 6. changes in gene expression without a permanent modification of DNA sequence
- 8. neurons that do not connect with other neurons undergo programmed cell death
- 10. genetic information flows from DNA to RNA to protein
Down
- 1. the production of new cells in the brain
- 2. the process by which glia produce the fatty sheath that covers the axons of some neurons
- 3. traits controlled by a single gene
- 4. the movement of neurons and glia to their eventual locations
- 7. formation of the synapses between neurons
- 9. permanent change in DNA
