Module #7 Vocab. Flashcards
Antibodies
Specialized proteins that aid in destroying infectious agents.
Anticodon
A three- nucleotide base sequence on tRNA.
Centromere
The reign that joins two sister chromatids.
Chromosome
DNA coiled around and supported by proteins , found in the nucleus of the cell.
Codon
A sequence of three nucleotide bases on mRNA that refers to a specific amino acid.
Diploid cell
A cell with chromosomes that come in homologous pairs.
Diploid number (2n)
The total number of chromosomes in a diploid cell
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 Preston’s behavioral choices.
Gametes
Haploid cells (n) produced by diploid cells (2n) for the purpose of sexual reproduction.
Gene
A section of DNA that codes for the production of a protein or a portion of a protein, thereby causing a trait.
Genetic factors
The general guideline of traits determined by a person’s DNA
Genetics
The science that studies how characteristics get passed from parent to offspring
Haploid cell
A cell that has only one representative of each chromosome pair.
Haploid number (n)
The number of homologous pairs in a diploid cell.
Interphase
The time interval between cellular reproduction.
Karyotype
The figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs.
Meiosis
The process by which a diploid (2n) call forms gametes (n).
Messenger RNA
The RNA that performs transcription.
Mitosis
A process of asexual reproduction in eukaryotic cells.
Mother Cell
A cell ready to begin reproduction, containing duplicated DNA and centrioles.
Spiritual Factors
The factors in a person’s life that are determined by the quality of his or her relationship with God.
Vaccine
A weakened or inactive version of a pathogen that stimulates the body’s production of antibodies which can aid in destroying the pathogen.
Virus
A non-cellular infectious agent that has two characteristics: (1) it has material (RNA or DNA) inside a protective protein coat. (2) it cannot reproduce on its own.
