- 2. a vital compound in biological systems, essential for bone health, energy production, and DNA/RNA structure
- 4. a relationship, often between structures or sequences, where each part fits precisely with the other, much like a lock and key, following specific pairing rules
- 8. the final stage of cell division in both mitosis and meiosis
- 10. refers to the DNA molecule's three-dimensional structure, a twisted ladder shape formed by two intertwined strands of nucleotides held together by hydrogen bonds between specific base pairs
- 11. a purine base, one of the four main nucleobases found in DNA and RNA
- 13. refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait
- 14. Interphase consists of the first growth (G1 phase), Synthesis (S phase), and the second growth (G2 phase) phases
- 15. a fundamental chemical compound, specifically a pyrimidine base, that's one of the four nitrogenous bases found in DNA and RNA.
- 17. the process where the cytoplasm of a cell divides after nuclear division, resulting in two separate daughter cells
- 18. the period in the cell cycle when a cell is not actively dividing
- 20. makes one of the building blocks of DNA and RNA
- 24. they exert authority, control, and influence over others, often displaying assertiveness, confidence, and a strong presence, tending to take charge and make decisions decisively
- 25. a permanent change in an organism's DNA sequence
- 26. an individual possessing two identical versions (alleles) of a gene, one inherited from each parent
Down
- 1. the process by which a cell makes an RNA copy of a piece of DNA
- 3. a pyrimidine base and one of the four nucleotide bases that make up DNA
- 5. the initial phase of mitosis (cell division) and meiosis I, where chromosomes condense and become visible, the nuclear envelope breaks down, and the mitotic spindle begins to form
- 6. a stage in both mitosis and meiosis where chromosomes, having condensed and become visible, align along the center of the cell at the metaphase plate
- 7. an individual carrying two different versions (alleles) of a gene for a particular trait
- 8. the process where a cell uses the information carried by a messenger RNA (mRNA) molecule to build a protein
- 9. the stage where sister chromatids separate and move to opposite poles of the cell, ensuring each daughter cell receives a complete set of chromosomes
- 12. a breeding experiment involving two organisms that are heterozygous (carrying two different alleles) for two different traits, examining how those traits are inherited and combined in the offspring
- 16. a basic building block of DNA and RNA, the molecules that carry genetic information
- 19. a chemical element; it has symbol N and atomic number 7.
- 21. plays a crucial role in translating That information into proteins, acting as a messenger and carrying out various cellular processes
- 22. a sweet, crystalline substance that serves as a primary source of energy for living organisms
- 23. a fundamental process in which a single cell divides into two identical daughter cells, each containing the same number and type of chromosomes as the parent cell
