Across
- 3. The process where DNA is copied into RNA, which is like creating a set of instructions to take to the “protein-making factory.”
- 7. A molecule in your cells that carries instructions for how your body works and what traits you have, like a recipe book for life.
- 10. The process in cells where RNA is used to build proteins (like following instructions to make a protein).
- 11. type of allele that always shows up in an organism’s traits if it is present (represented by a capital letter, like A).
- 13. A characteristic that an organism has, like eye color, hair type, or height.
- 16. When an organism has two different alleles for a trait (like Aa).
- 17. The genetic makeup of an organism; the combination of alleles (like AA, Aa, or aa).
- 18. A small section of DNA that determines a specific trait, like the instructions for eye color.
Down
- 1. A type of allele that only shows up when no dominant allele is present (represented by a lowercase letter, like a).
- 2. When an organism has two of the same alleles for a trait (like AA or aa).
- 4. A tool that helps predict the possible traits of offspring by showing how alleles can combine.
- 5. Molecules that build and repair your body and help it function, like tiny machines that do important jobs.
- 6. A thread-like structure made of DNA that holds many genes. Humans have 46 chromosomes in most cells.
- 8. Acids Small molecules that are the building blocks of proteins, like individual beads in a necklace.
- 9. A molecule that acts like a messenger between DNA and the parts of the cell that build proteins.
- 12. A change in DNA that can sometimes lead to a new or different trait.
- 14. The physical appearance or traits of an organism based on its genotype (like having brown or blue eyes).
- 15. A different version of a gene; for example, a gene for eye color might have a blue allele or a brown allele.
