Across
- 2. This type of mutation is passed on to one’s offspring
- 3. This is a highly conserved stretch of DNA sequence present in Hox protein coding sequences
- 5. When a cell’s fate is determined by a message it receives from another cell, cell to cell ______ has occurred
- 8. A _______ mutation makes the phenotype of another mutation more dramatic
- 10. This technology uses small DNA probes to study the gene expression of many genes simultaneously by assaying all mRNA expressed in a tissue.
- 13. This is the process in which cells begin to express different sets of genes and ultimately become different tissue types.
- 15. Programmed cell death, either during development or as “cellular suicide” for diseased cells
- 16. This type of mutation affects more than one phenotype
- 17. Tumor ________ genes are genes which are recessive when mutated, but can produce a cancer
- 18. This type of mutation makes cells more likely to accumulate genetic errors.
- 19. Signal _______ is the general word for how an extracellular signal is passed through the cell membrane to effect things inside the cell
Down
- 1. In ______ mutants, the identity of one body structure has been changed into another.
- 4. In ________ division, the two daughter cells of mitosis and cytokinesis are nonidentical and can have different cell fates
- 6. This type of gene is dominant when mutated and can produce a cancer
- 7. Cells acquire different tissue identities and fates by expressing different ____ factors
- 9. This type of gene makes a product that is deposited into an egg by the female
- 11. This interesting property of Hox genes means that their expression order along the body of an animal is the same order they are found in on the chromosome.
- 12. These genes encode proteins with functions necessary for cellular upkeep, metabolism and protein synthesis
- 14. A cell that is going to divide must pass through several of these potential stopping points throughout the cell cycle
