- Most DNA is found in the nucleus.
- You inherit 23 chromosomes from your father and 23 from your mother, for a total of 46 chromosomes.
- If you are male, you have one X chromosome and one Y chromosome (XY). If you are female, you have two X chromosomes (XX).
- DNA contains instructions for making proteins.
- Proteins have many roles in the body, such as building tissues, enzymes, and cell signaling.
- Sections of DNA that contain instructions for making proteins are called genes.
- T pairs with A, and G pairs with C.
- The base pairs that would pair with the sequence A-T-G-A-C would be T-A-C-T-G.
