6. One of four nitrogenous bases that make up the structure of DNA, notated by the letter G.
9. a distinct sequence of nucleotides forming part of a chromosome that determines traits passed from parent to offspring
13. Scientist who discovered that genes were a chemical substrate/factor, leading to transformation
14. virus that infects bacteria, used by Hershey and Chase to prove that DNA is in fact genetic material, not protein.
15. Type of cell division that copies genetic information
17. bacteria strain changes into another
21. One of four nitrogenous bases that make up the structure of DNA, notated by the letter A.
22. DNA makes a copy of itself
23. Place in the cell where genetic information is stored in the form of DNA.
25. Deoxyribose Nucleic Acid

1. These bonds form between certain nitrogenous bases (a=t, c=g).
2. principal enzyme involved in DNA replication
3. One of four nitrogenous bases that make up the structure of DNA, notated by the letter T.

7. Scientist who was left out of the discovery of the double helix structure of DNA by James Watson and Francis Crick.
8. change in the genetic material
10. A chemical made up of a deoxyribose, a phosphate group, and a nitrogenous base.
11. hydrogen bonds can form only between certain bases in DNA using Chargaff’s rules (%a=%t and %C=%g).
12. decoding of an mRNA message into a protein
16. three parts: a deoxyribose sugar, a phosphate group, and a nitrogenous base

19. Scientist whose team found that DNA is the most important molecule for transformation
20. cells become specialized in structure and function
24. The scientist for whom the rules for base pairs (%a=%t and %C=%g) is named.
