| Question | Answer |
| What happens to the cells of the body during the growth of a child? | The cells of a growing child divide to make more cells, and those cells grow to become the same size as the cells were just before they divided |
| A cell with 10 chromosomes undergoes mitosis, how many daughter cells are created? Each cell has how many chromosomes? | 2 cells are created, each with 10 chromosomes |
| What do Chromosomes and DNA contain? | Genetic Information |
| If a skin cell contains 60 chromosomes, how many chromosomes will be in the 2 daughter cells after the original cell has undergone mitosis? WHY??? | 60, because the original cell replicates its DNA and then when it divides each daughter cell ends up with the same amount of DNA as the original cell. |
| What is not associated with mitosis? | Production of egg and sperm |
| What do you call a section of a chromosome that codes for a trait? | Gene |
| What is a Gene? | A segment of DNA that controls body structure and function. |
| What is DNA? | Deoxyribonucleic Acid: a helical molecule that carries the genetic information of an organism and is passed from parent to offspring |
| A human cell has 23 pairs of Chromosomes for a total of 46 chromosomes. At the end of mitosis a new cell will have? | 23 pairs of chromosomes, 46 total chromosomes |
| What is a chromosome? | Condensed or compact rod of DNA that carries genetic information. |
| What is mitosis? | Cell division which replicated chromosomes divide leading to identical daughter cells with the same number of chromosomes and same genetic composition as the parent cell |
| Draw a diagram of mitosis: show the cell in interphase, show the DNA replicate, show DNA condense, show Chromosomes line up in the middle, show the cell divide into two cells |
