Cell Cycle

1. always pairs with cytosine
3. having one set of genes
7. converting the DNA code into a protein
8. new chromosomes begin to uncoil, new nuclear membranes form and 2 new nuclei form
10. each section of DNA that codes for a unique protein
11. the process that cells use to make RNA copies of a gene
12. always pairs with thymine
14. chromosomes line up in the middle of each cell
15. always pairs with adenine
16. a sperm or egg cell
18. process of the cell cycle that ensures that each new daughter cell producxed has the same number & kinds of genes as the parent cell
19. matches codon on the mRNA
20. the process that reduces by half the amount of DNA in an egg or sperm cell

2. sister chromatid pairs divide into separate chromosomes
4. first phase of the cell cycle in which the cell grows and carries out its normal function
5. diploid cell that results from fertilization
6. always pairs with guanine
9. acids the molecules used to build proteins
13. subunits of the long DNA molecule that consist of a sugar, phosphate and base
15. the DNA copying process
17. final stage of the cell cycle
