- G2 phase
- somatic cells
- a A cell containing two sets of chromosomes (2n), one set inherited from each parent.
- b Any cell in a multicellular organism except a sperm or egg or their precursors.
- 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.
- d The spread of cancer cells to locations distant from their original site.
- 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
- 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).
- A display of the chromosome pairs of a cell arranged by size and shape.
- The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
- 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.
- A cell containing only one set of chromosomes (n).
5 True/False Questions
chromatin → The 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.
binary fission → A 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.
gene locus → 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.
kinetochore → In 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.
gametes → The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
