Reproduction Defs
Exploring Creation with Biology - Module 7 (Cellular Reproduction) Definitions
Question | Answer |
---|---|
Genetics | The science that studies how characteristics get passed from parent to offspring |
Genetic factors | The general guideline of traits determined by a person's DNA |
Environmental factors | Those "non-biological" factors that are involved in a person's surroundings such as the nature of the person's parents, the person's friends, and the person's behavioral choices |
Spiritual factors | The quality of a person's relationship with God |
Gene | A section of DNA that codes for the production of a protein or a portion of a protein, thereby causing a trait |
Chromosome | A strand of DNA coiled around and supported by proteins, found in the nucleus of the cell |
Mitosis | The duplication of a cell's chromosomes to allow daughter cells to receive the exact genetic makeup of the parent cell |
Interphase | The time interval between cellular reproduction |
Centromere | Constricted region of a chromosome and the point at which duplicate DNA strands attach themselves |
Mother cell | A cell ready to begin reproduction, containing duplicate DNA and centriole |
Karyotype | The figure produced when the chromosomes of a species during metaphase are arranged according to size |
Diploid cell | A cell whose chromosomes come in homologous pairs |
Haploid cells | Cells that have only one of each chromosome |
Diploid chromosome number | The total number of chromosomes in a diploid cell |
Haploid chromosome number | The number of homologous pairs in a diploid cell |
Meiosis | The process by which a diploid (2n) cell forms four gametes (n) |
Gametes | Haploid cells (n) produced by diploid cells (2n) for the purpose of reproduction |
Virus | A non-cellular infectious agent that has two characteristics: (1) It has genetic material inside a protective protein coat; (2) It cannot reproduce itself |
Antibodies | Specialized proteins that aid in destroying infectious agents |
Vaccine | A weakened or inactive version of a virus that stimulates the body's production of antibodies which can destroy the virus |
