3. an unstable element that emits radiation
6. a solution containing 2 or more substances
9. a single strand of base pairs complements made by RNApolymerase
11. makes up 98.5% of the body oxygen, carbon, hydrogen, nitrogen, calcium, phosphate
12. when ribosomes read the amino acid code to create a specific protein
13. when one phosphate group bonds to another phosphate group
14. a bond between 2 polar opposite molecules but stable and weakest bond
16. found abundantly in the body contains a phosphate group sugar and adenosine
19. a group of 3 consecutive bases
20. the last occupied shell in an element

1. when DNA is coiled tightly around histones and the genes are inaccessible/silent
2. used almost immediately when created breaks down in water and releases energy
4. there are 3000000000 base pairs that make up our genes throughout the 23 chromosomes
5. a molecule that does not contain carbon
7. a heterogenous solution in a semi-liquid jelly like state
8. a pure solution that helps the body maintain body temp is polar and allows cohesion
10. something formed by a neutralization reaction between a base and acid
12. when the mRNA copies the DNA into a readable script
15. the enzyme that unwinds the double helix in DNA to copy base pairs
17. a truely stable element has 8 electrons in its outside shell
18. a solution that is uniformly combined throughout
