  1. 8. G2: Key phases in the cell cycle where the cell grows and checks readiness for division.
  2. 9. Bases that pair together in DNA or RNA—like adenine with thymine.
  3. 12. Synthesis: The process of creating proteins through transcription and translation.
  4. 13. The two fundamental types of nucleic acids, carrying genetic information.
  5. 15. The part of the cell cycle where the cell grows and prepares for division.
  6. 16. Part of the nucleotide structure; deoxyribose in DNA and ribose in RNA.
  7. 19. Having two different alleles for a particular gene.
  8. 22. The genetic trait that is expressed when at least one dominant allele is present.
  9. 24. The first stage of mitosis where chromosomes become visible and the nuclear envelope starts dissolving.
  10. 25. A nitrogen base that pairs with thymine in DNA or with uracil in RNA.

  1. 1. The process of copying DNA into RNA.
  2. 2. Helix: The spiral shape of the DNA molecule.
  3. 3. Changes in DNA that can result in genetic variation or disease.
  4. 4. Having two identical alleles for a particular gene.
  5. 5. The stage in mitosis where chromatids are pulled apart to opposite ends of the cell.
  6. 6. The process where the cytoplasm divides, creating two daughter cells.
  7. 7. A type of cell division that results in two identical daughter cells.
  8. 8. A nitrogen base that pairs with cytosine in DNA or RNA.
  9. 10. The basic unit of DNA or RNA, made up of a sugar, a phosphate group, and a nitrogenous base.
  10. 11. Types of genetic crosses used to study inheritance patterns.
  11. 14. Bases: The building blocks of DNA and RNA that form the “rungs” of the genetic ladder.
  12. 17. A genetic trait that is only expressed if two recessive alleles are present.
  13. 18. A component of the nucleotide backbone, essential for the DNA structure.
  14. 20. The stage in mitosis where chromosomes align in the middle of the cell.
  15. 21. The final phase of mitosis where the nuclear envelope reforms around separated chromosomes.
  16. 23. A nitrogenous base found in DNA, pairs with adenine.
  17. 26. The process where RNA is used to synthesize proteins.
