| 1393153766 | What are the hydrogen bonds between? | The bases (A.T.C.G) | 6 | |
| 1393153767 | A's & T's can only bond how many times? | 2 | 7 | |
| 1393153768 | G's & C's can bond how many times? | 3 | 8 | |
| 1393153769 | First step of DNA Replication? | Uncoiled- the molecules have to be exposef to the enzymes | 9 | |
| 1393153770 | Second step of DNA Replication? | Unzipped- hydrogen bonds get dissolved | 10 | |
| 1393153771 | Who dissolves the hydrogen bonds in the DNA Replication? | DNA Helacies | 11 | |
| 1393153772 | Third step of DNA Replication? | DNA Polimerazes- the cell is then ready to split | 12 | |
| 1393153773 | Prokaryotes reproduces how? | asexually | 13 | |
| 1393153774 | Binary fission occurs in what? | Prokaryotes | 14 | |
| 1393153775 | How long is prokaryotes life? | 1 hour | 15 | |
| 1393153776 | What shape in DNA | Circular | 16 | |
| 1393153777 | Step one in binary fission? | Circular DNA attaches to membrane | 17 | |
| 1393153778 | Step two in binary fission? | Cell is expanding. | 18 | |
| 1393153779 | In what step of binary fission how dna been replicated? | Step two | 19 | |
| 1393153780 | Step three in binary fission? | puts more phospholipids into membrane | 20 | |
| 1393153781 | Step 4 in binary fission? | Plasma membrane gets so big b/c of all of the phospholipids that it encloses around each set of DNA | 21 | |
| 1393153782 | Step 5 in binary fission? | Membrane pinches the 2 cells apart, the parent-cell completes the division | 22 | |
| 1393153783 | cells in the what go through meiosis to produce gamates? | Asexually | 23 | |
| 1393153784 | cells in the what go through meiosis to produce gamates? | Ovaries and testies | 24 | |

| 1393153786 | What is the spindle made up of? | Spindle shows up, nucleus disappears | 26 | |
| 1393153787 | What happens in metaphase 1? | chromosome pushed to the equator | 27 | |
| 1393153788 | what happens in anaphase 1? | Chromosomes are pushed apart | 28 | |
| 1393153789 | What happens in telophase 1? | Cytokinesis happens here (split) | 29 | |
| 1393153790 | what happens in prophase 2? | spindle reforms & attach to the sister chromotids | 30 | |
| 1393153791 | what happens in metaphase 2? | sisters pushed to the equator | 31 | |
| 1393153792 | what happens in anaphase 2? | sister chromotids are separated | 32 | |
| 1393153793 | what happens in telophase 2? | cells start splitting stages, nucleus reappears | 33 | |
| 1393153794 | cytokinesis results in how many haploid cells? | 4 | 34 | |
| 1393153795 | a scar/bump on the chromosome when they cross over is called what? | chiasma | 35 | |
| 1393153796 | Where does genetic variability happen at? | in prophase 1 & metaphase 1 | 36 | |
| 1393153797 | what is it called when sisters fail to split? | nondisjunction | 37 | |
| 1393153798 | what are white blood cells called? | karotyping | 38 | |
| 1393153799 | what are chromosomes? | long, thing pieces of DNA | 39 | |
| 1393153800 | In mitosis....Interphase. name the steps | G1, S phase, G2 | 40 | |
| 1393153801 | What happens in G1? | Cell grows | 41 | |
