5 Matching Questions

  1. G2 phase
  2. somatic cells
  3. metastasis
  4. diploid
  5. genome
  1. a A cell containing two sets of chromosomes (2n), one set inherited from each parent.
  2. b Any cell in a multicellular organism except a sperm or egg or their precursors.
  3. c The genetic material of an organism or virus; the complete complement of an organism's or virus's genes along with its noncoding nucleic acid sequences.
  4. d The spread of cancer cells to locations distant from their original site.
  5. e The second gap, or growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.

5 Multiple Choice Questions

  1. An ordered sequence of events in the life of a cell, from its origin in the division of a parent cell until its own division into two. The eukaryotic is composed of interphase (including GG1, S, and GG2 subphases) and M phase (including mitosis and cytokinesis).
  2. A display of the chromosome pairs of a cell arranged by size and shape.
  3. The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
  4. The generation of offspring from a single parent that occurs without the fusion of gametes (by budding, division of a single cell, or division of the entire organism into two or more parts). In most cases, the offspring are genetically identical to the parent.
  5. A cell containing only one set of chromosomes (n).

5 True/False Questions

  1. chromatinThe complex of DNA and proteins that makes up eukaryotic chromosomes. When the cell is not dividing, it exists in its dispersed form, as a mass of very long, thin fibers that are not visible with a light microscope.

          

  2. binary fissionA method of asexual reproduction by "division in half." In prokaryotes, it does not involve mitosis, but in single-celled eukaryotes that undergo this, mitosis is part of the process.

          

  3. gene locusThe genetic material of an organism or virus; the complete complement of an organism's or virus's genes along with its noncoding nucleic acid sequences.

          

  4. kinetochoreIn organisms (plants and some algae) that have alternation of generations, the multicellular haploid form that produces haploid gametes by mitosis. The haploid gametes unite and develop into sporophytes.

          

  5. gametesThe diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
