Biology: DNA

4. Deoxyribose Nucleic Acid
6. One of four nitrogenous bases that make up the structure of DNA, notated by the letter A.
9. Scientist who discovered that genes were a chemical substrate/factor, leading to transformation
11. Place in the cell where genetic information is stored in the form of DNA.
14. helix The structure of DNA, discovered by Franklin, Watson, and Crick.
15. DNA makes a copy of itself
18. bacteria strain changes into another
20. Scientist who was left out of the discovery of the double helix structure of DNA by James Watson and Francis Crick.
23. One of four nitrogenous bases that make up the structure of DNA, notated by the letter C.
25. These bonds form between certain nitrogenous bases (a=t, c=g).

1. a distinct sequence of nucleotides forming part of a chromosome that determines traits passed from parent to offspring
2. pairing hydrogen bonds can form only between certain bases in DNA using Chargaff’s rules (%a=%t and %C=%g).
3. One of four nitrogenous bases that make up the structure of DNA, notated by the letter G.
5. change in the genetic material
7. A chemical made up of a deoxyribose, a phosphate group, and a nitrogenous base.
8. decoding of an mRNA message into a protein
10. virus that infects bacteria, used by Hershey and Chase to prove that DNA is in fact genetic material, not protein.
12. Type of cell division that is important for sorting genetic information
13. The scientist for whom the rules for base pairs (%a=%t and %C=%g) is named.
16. Scientist whose team found that DNA is the most important molecule for transformation
17. three parts: a deoxyribose sugar, a phosphate group, and a nitrogenous base
19. cells become specialized in structure and function
21. polymerase principal enzyme involved in DNA replication
22. Type of cell division that copies genetic information
24. One of four nitrogenous bases that make up the structure of DNA, notated by the letter T.
