Across
- 4. An alternative version of a specific gene that is on the same spot on a chromosome. The gene codes for eye color, while the allele codes only the color brown eyes.
- 5. Are thread-like structures in the cell nucleus that are coiled around proteins. They function as storage units for DNA. Humans have 23 pairs of chromosomes.
- 6. It is the “blueprint” molecule that stores all your genetic information.
- 7. An allele that expresses its effect only if two copies are present. For example attached ear lobes.
- 8. Are the physical or behavioral characteristics that are passed down from parents to their offspring.
- 10. Also called inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction.
Down
- 1. Are the basic building blocks of DNA. Made of three main parts: nitrogenous base, a sugar, and a phosphate group.
- 2. Are made from reading segments of DNA. They express the traits you have.
- 3. Is the entire set of DNA found in a cell.
- 6. An allele that expresses its effect even if only one copy is present. For example brown eye color over blue eye color.
- 9. A segment of DNA. They are the basic unit of heredity. They provide instructions to build proteins.
