Across
- 5. a genetic mix between 2 indivisuals with homogezygous genotypes
- 7. a term used to describe the physical structure of DNA
- 9. the end of mitosis
- 12. chromosomes become attached to the spindle fibers
- 14. it is paired with adenine
- 18. having two different alleles of a particular gene or genes
- 20. it's between the first and second divisions of meiosis
- 21. takes place in the ribosome
- 23. it pairs with cytosine
- 24. a compound consisting of a nucleoside linked to a phosphate group
- 25. a gene that expresses itself more strongly
- 26. a form of phosphoric acid, which contains phosphorus
- 27. is when a cell makes an RNA copies of a piece of DNA
Down
- 1. having two identical alleles of a particular gene or genes
- 2. another word for sucrose
- 3. chromosomes move away from one another to opposite poles of the spindle
- 4. it pairs with guanine
- 6. can be found in a nucleus
- 8. when cytosine always combines with Guanine, and adenine always combines with thymine
- 10. cell division that creates two daughter cells
- 11. chromosomes move to opposite ends of the cell and two nuclei are formed
- 13. Gap 1 and Gap 2 phase
