1

Genetics

The science that studies how characteristics get passed from parent to offspring

2

Genetic Factors

The general guideline of traits 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 portion of protein, thereby causing a trait

6

Messenger RNA

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

Mother Cell

A cell ready to begin reproduction, containing duplicated DNA and centrioles

13

Centromere

The region that joins two sister chromatids

14

Karyotype

The figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs

15

Diploid cell

A cell with chromosomes that come in homologous pairs

16

Haploid Cell

A cell that has only one representative of each chromosome pair

17

Diploid Number 2n

The total number of chromosomes in a diploid cell

18

Haploid number n

The number of homologous pairs in a diploid cell

19

Meiosis

The process by which a diploid (2n) cell forms gametes (n)

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 it's own.

21

Antibodies

Specialized proteins that aid in destroying infectious agents

22

Vaccine

A weakened or inactive version of a pathogen that stimulates the body's production of antibodies which can aid in destroying the pathogen

23

Phases of Mitosis

Interphase (Not really) Prophase, Metaphase, Anaphase, Telophase,
