Across
- 5. - Genetic Material
- 8. - "same alleles" or "identical alleles" for a specific gene.
- 11. - one that masks the expression of another, recessive allele
- 12. - Gap 1 Phase
- 13. - The cell's 'daily living' phase, where it grows, replicates DNA, and prepares for division
- 14. - adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G)
- 16. - A type of nucleic acid, a copy of DNA
- 18. - a change in the DNA sequence, potentially leading to altered traits or diseases, caused by various factors like errors during replication or exposure to mutagens
- 20. - points to the process where a cell uses the messenger RNA (mRNA) to build a protein
- 22. - it involves ribosomes
- 24. - having two different alleles for a specific trait
- 25. - could relate to DNA, RNA, ATP, phospholipids, or the phosphorus cycle
- 27. - the final stage of mitosis and meiosis, the separated chromosomes arrive at opposite poles, the nuclear envelope reforms around each set of chromosomes, and the mitotic spindle breaks down, marking the end of nuclear division.
- 28. - a nitrogenous base found in DNA and RNA, forming base pairs with guanine
- 29. - it's one of the four nucleobases (along with adenine, cytosine, and thymine) found in DNA and RNA, and it always pairs with cytosine (C).
- 30. - a nucleobase in DNA, represented by the letter T
Down
- 1. - they involve the inheritance of two traits, each with two alleles, resulting in a predictable 9:3:3:1 phenotypic ratio in the offspring when two heterozygous individuals are crossed.
- 2. - two linked strands winding around each other, resembling a twisted ladder.
- 3. - a cross between two individuals that differ in only one trait, focusing on the inheritance of that single gene.
- 4. - meaning "cell movement," is the process where the cytoplasm of a cell divides, resulting in two daughter cells, following nuclear division (karyokinesis).
- 6. - adenine (A), guanine (G), cytosine (C), and thymine (T)
- 7. - the fundamental building block of nucleic acids (DNA and RNA), composed of a nitrogenous base, a pentose sugar (deoxyribose in DNA, ribose in RNA), and a phosphate group.
- 9. - Growth 2 phase
- 10. - a trait is only expressed when an individual has two copies of the recessive allele
- 15. - it's a nitrogenous base, specifically a purine, found in DNA and RNA, and it always pairs with thymine (in DNA) or uracil (in RNA).
- 17. - the appearance of chromosomes
- 18. - chromosomes, which are fully condensed, align along the metaphase plate (the cell's equator) and are attached to spindle fibers, preparing for separation.
- 19. - points to the process of a cell making an RNA copy of a DNA sequence
- 21. - the suffix "-ose" (like in glucose, fructose, sucrose) or the fact that sugars are carbohydrates
- 23. - chromosomes condense and become visible, the nuclear envelope breaks down, the nucleolus disappears, and the mitotic spindle begins to form.
- 26. - the sister chromatids (now called chromosomes) separate and are pulled towards opposite poles of the cell
