  1. Genetics
    The science that studies how characteristics get passed from parent to offspring
  2. Genetic Factors
    The general guideline of triats determined by a person's DNA
  3. Environmental factors
    Those "nonbiological" 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
  4. Spiritual factors
    The factors in a person's life that are determined by the quality of his or her relationship with God
  5. Gene
    A section of DNA that codes for the production of a protein or a portion of protein, thereby causing a trait
  6. Messenger RNA (mRNA)
    The RNA that performs transcription
  7. Anticodon
    A three-nucleotide base sequence on tRNA
  8. Codon
    A sequence of three nucleotide bases on mRNA that refers to a specific amino acid
  9. Chromosome
    DNA coiled around and supported by proteins, found in the nucleus of the cell
  10. Mitosis
    A process of asexual reproduction in eukaryotic cells
  11. Interphase
    The time interval between cellular reproduction
  12. Centromere
    The region that joins two sister chromatids
  13. Karyotype
    The figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs
  14. Diploid cell
    A cell with chromosomes that come in homologous pairs
  15. Haploid cell
    A cell that has only one representative of each chromosome pair
  16. Diploid number (2n)
    The total number of chromosomes in a diploid cell
  17. Hapliod number (n)
    The number of homologous pairs in a diploid cell. ( half the diploid number )
  18. Meiosis
    The process by which a diploid (2n) cell forms gametes (n)
  19. Gametes
    Haploid cells (n) produced by diploid cells (2n) for the purpose of sexual reproduction
  20. 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
  21. Antibodies
    Specialized proteins that aid in destoying infectious agents
  22. Vaccine
    A weakened or inactive version of the pathogen that stimulates the body's production of antibodies which can aid in destroying the pathogen
