- 2. A form of dominant inheritance where two traits blend together
- 5. Having a single set of chromosomes (n) instead of the usual paired set (2n).
- 9. An enzyme involved in DNA replication that unwinds the double helix.
- 10. A thread-like structure of DNA and proteins that carries genetic information in the cell.
- 11. Cell division that produces four genetically different daughter cells, used in the formation of gametes.
- 13. Cell division that results in two identical daughter cells, used for growth and repair.
- 15. An enzyme involved in DNA replication and transcription that synthesizes new DNA or RNA strands.
- 16. When two alleles for a gene are expressed equally in a heterozygous individual, resulting in a distinct phenotype.
- 20. The process of protein synthesis where the information in RNA is used to build a protein.
- 21. Capable of being transmitted from one person to another, usually through direct or indirect contact.
- 23. Reproduction without the involvement of gametes or the union of genetic material from two parents.
- 24. The process by which genetic information in DNA is copied into RNA.
- 26. This structure of DNA provides the blueprint for life. (2 words)
- 27. The reproductive structure of flowering plants, typically containing petals, sepals, stamens, and pistils.
- 28. Practices that promote health and prevent the spread of diseases.
- 30. A hormone involved in childbirth and social bonding.
- 31. The transfer of pollen from the male reproductive organ to the female reproductive organ in plants.
- 32. One of the alternative forms of a gene, occupying a specific position on a chromosome.
- 33. An organism that has had genes from another species introduced into its genome.
- 34. Single-celled microorganisms that can be found in various environments.

- 1. An agent or factor that can cause mutations in DNA.
- 3. This is produced in the ribosomes via interactions between M-RNA and T-RNA
- 4. The building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
- 6. An infectious agent that can replicate only inside the cells of living organisms.
- 7. The ability of an organism to withstand the effects of a particular pathogen or drug.
- 8. A segment of DNA that contains the instructions for building a specific protein or performing a specific function.
- 10. The exchange of genetic material between homologous chromosomes during meiosis.
- 12. Relating to the cells of the body that are not involved in reproduction.
- 14. A change in the DNA sequence that can lead to genetic variation.
- 15. A disease-causing organism or agent, such as a bacterium or virus.
- 17. Having two sets of chromosomes (2n).
- 18. An organism that is genetically identical to its parent.
- 19. An organism, often an insect, that carries and transmits disease-causing pathogens.
- 22. A reproductive cell (sperm or egg) that contains half the number of chromosomes as a body cell.
- 25. The process by which DNA makes an identical copy of itself.
- 29. The variety and variability of life forms within a given ecosystem, biome, or planet.
