gentetics
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 persons surroundings such as the nature of a persons parents, the persons friends, and the person behavioral choices
spiritual factors
the factors in a persons 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
anitcodon
a three- nucleotide base sequence on tRNA
codon
a sequence of three nucleotide bases on mRNA that refers o a specific 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
mother cell
a cell ready to begin reproduction containing duplicated DNA and centrioles
centromere
he region that joins two sister chromatids
karyotype
the figure produced when the chromosomes of a species during metephase 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
diploid number (2n)
the total number of chromosomes in a diploid cell
haploid number (n)
the number of homologous pairs in a diploid cell
meiosis
the process by which a diploid (2n) cell forms gametes (n)
gamates
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
vaccine
a weakened or inactive version of a pathogen that stimulates that body’s production of antibodies which can aid in destroying the pathogen
