3. Bases that pair together in DNA or RNA—like adenine with thymine.
5. Synthesis The process of creating proteins through transcription and translation.
7. A component of the nucleotide backbone, essential for the DNA structure.
11. The final phase of mitosis where the nuclear envelope reforms around separated chromosomes.
14. The stage in mitosis where chromosomes align in the middle of the cell.
17. The genetic trait that is expressed when at least one dominant allele is present.
18. The process where the cytoplasm divides, creating two daughter cells.
19. Having two different alleles for a particular gene.
21. A type of cell division that results in two identical daughter cells.
22. A nitrogen base that pairs with cytosine in DNA or RNA.

1. The first stage of mitosis where chromosomes become visible and the nuclear envelope starts dissolving.
2. The process of copying DNA into RNA.
4. Helix The spiral shape of the DNA molecule.
6. Types of genetic crosses used to study inheritance patterns.
8. The process where RNA is used to synthesize proteins.
9. Changes in DNA that can result in genetic variation or disease.
10. A genetic trait that is only expressed if two recessive alleles are present.
12. Having two identical alleles for a particular gene.
13. A nitrogen base that pairs with guanine in DNA or RNA.
15. A nitrogen base that pairs with thymine in DNA or with uracil in RNA.
16. The stage in mitosis where chromatids are pulled apart to opposite ends of the cell.
20. Part of the nucleotide structure; deoxyribose in DNA and ribose in RNA.
23. The basic unit of DNA or RNA, made up of a sugar, a phosphate group, and a nitrogenous base.
