TermDefinition
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 factors in a person's life that are determined by the quality of his or her relationship with God (
Gene A section of DNA that codes for the production of a protein or a portion of protein, thereby causing a trait
Messenger RNA The RNA that performs transcription
Anticondon A three-nucleoctide sequence on tRNA
Codon A sequence of three nucleotides on mRNA that refers to a specific type of amino acid
Chromosome DNA coiled around and supported by proteins, found in the nucleus of the cell
Mitosis A process of asexual reproduction in eukaryotic cells
Interphase The time interval between cellular reproduction (
Centromere The region that joins two sister chromatids
Mother Cell 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 their homologous pairs
Diploid Cell A cell with chromosomes that come in homologous pairs
Haploid Cell A cell that has only one representative of each chromosome pair
Dioploid Number The total number of chromosomes in a diploid cell
Haploid Numer 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 sexual reproduction
Virus A non-cellular infectious agent that has two characteristics: 1.) It has genetic material (RNA or DNA) inside a protective protein coat 2.) It cannot reproduce on its own
Antibodies Specialized proteins that aid in destroying infectious agents
