Chapter 6 Genetics
Across
- 4. end result of meiosis
- 5. prophase chromosomes pair up with matching partners and swap parts
- 8. Males generate germ cells called spermatazoa (sperm), through
- 10. division of somatic cells; new cells receive the same number of chromosomes
- 11. two step cell division
- 12. four bases in DNA (first letters), form a double helix
- 14. Transfers amino acids to make proteins.
- 16. identical allelic genes are?
- 17. part of the robosomes, where the proteins are built.
- 20. several amino acids form a
- 21. sequence of 3 bases
- 23. inactivated x chromosome forms a contracted structure known as a
- 24. Females generate germ cells called ova (egg) through
- 25. Prophase, metaphase, anaphase, telophase
- 26. Can duplicate itself
Down
- 1. mature germ cells (23 chromosomes)
- 2. 46 in the human body
- 3. trait or gene needs only one gene to exhibit the trait
- 6. trait or characteristic needs 2 genes to exhibit
- 7. Carries the message from the DNA to ribosomes
- 9. different allelic genes are?
- 10. how is mitochondrial DNA inherited
- 13. inherited abnormalities at the lvl of 1 or both allelic genes (# or structure)
- 15. genes that are located at the same lvl (locus)
- 18. primitive germ cells (46 chromosomes)
- 19. abnormalities that can be observed in a karotype
- 22. one or more polypeptides for a
