20
19 These coiled pieces of DNA can either be single or duplicated
21
20 What are chromosomes?
22
21 These pieces of DNA are identical copies of one another
23
22 What are sister chromatids?
24
23 The familiar x shaped chromosome that we see after replication
25

30
29 This process doubles the amount of DNA
31
30 What is DNA replication?
32
31 This enzyme breaks hydrogen bonds to separate the two strands of DNA
33
32 What is DNA helicase
34
33 This enzyme produces the new strands of DNA by adding complementary nucleotides to the old strand
35

38
37 What is 89?
39
38 This is split in DNA replication while sister chromatids are split in mitosis
40
39 What are the two strands of DNA or a DNA molecule?
41

42
41 What is mitosis or anaphase?
43
42 DNA is replicated in this phase of the cell cycle
44

50
49 What is 15?
51
50 The phosphate always bonds to this pentagonal shaped molecule
52
51 What is deoxyribose or sugar?
53
52 These are the bonds that hold together the backbone of DNA
54
