Across
- 3. the molecule inside cells that contains the genetic information responsible for the development
- 10. -a genetic change in which a piece of one chromosome breaks off and attaches to another chromosome
- 11. membranous true-like projections arising from the body of the neuron
- 12. - a chromosomal defect in which a segment of the chromosome breaks off and reattaches in the reverse direction
- 14. cell- a type of cell that receives ang sends messages from the body
- 17. division- the process by which a single parent cell splits to form new cells
- 18. the largest part of the brain
- 20. the long threadline part of a nerve cell which impulses the conducted from the cell body to other cells

- 24. part of nervous system consisting of sensory receptors received stimuli
- 25. a type of genetic change that involves the absence of a segment of DNA
- 26. body- the central part of a neuron that includes the nucleus but not the axons ang dendrites
- 27. the genetic code is the set of rules used by living cells to translate information encoded within genetic material
- 28. any change in the DNA sequence of a cell
- 29. the basic unit of heredity passed from parent to child
- 30. a type of mutation in which one nucleotide is replaced by a different nucleotide
