Biology Terms

2. Cells Non-reproductive cells that make up the majority of the body's cells.
5. 2 The second round of cell division in the reproductive cells, resulting in the production of gametes.
6. The genetic makeup of an individual.
7. Over The exchange of genetic material between homologous chromosomes during meiosis.
9. An allele that will be expressed if an individual has one copy of the allele.
11. The process of creating a complementary RNA copy from a DNA sequence.
13. A stage of cell division where the chromosomes line up at the center of the cell.
16. One of the two identical copies of DNA that make up a chromosome.
18. Alleles A gene that has more than two alleles.
19. The final stage of cell division, where the nuclear envelope reforms and the chromosomes uncoil.
21. Deoxyribonucleic acid
22. An allele that will only be expressed if an individual has two copies of the allele.
23. An individual that has two different alleles of a gene.
25. Having two different alleles of a gene.
28. A thread-like structure that carries genetic information in the nucleus of a cell.
29. The process of building a protein from an RNA sequence.
30. A stage of cell division where the sister chromatids separate and move to opposite ends of the cell.

1. A variant of a gene that occupies a specific location on a chromosome.
3. Programmed cell death, a process by which cells self-destruct.
4. Cycle A series of events that take place in a cell, leading to its division and replication.
5. 1 The first round of cell division in the reproductive cells, resulting in cells with half the number of chromosomes.
6. The study of heredity, genes, and variation.
8. The longest stage of the cell cycle, during which the cell grows, replicates its DNA, and prepares for cell division.
10. Dominance A situation where one allele does not completely dominate the other allele.
12. An allele that has an equal effect on the phenotype, resulting in a combination of the two alleles.
14. A characteristic or feature of an individual.
15. A process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
17. Having two copies of the same allele of a gene.
20. The reproductive cells, such as sperm and egg cells, that contain half the number of chromosomes.
24. physical and behavioral characteristics of an individual that result from the interaction of their genotype and the environment.
26. Ribonucleic acid, a molecule that plays a crucial role in protein synthesis and other cellular processes.
27. A unit of heredity that carries information from one generation to the next.
30. Acid A building block of proteins that comes from mRNA (codon).
