- G2 phase
- a The second gap, or growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.
- b in a duplicated chromosome, the region on each sister chromatid where they are most closely attached to each other by proteins that bind to specific DNA sequences; this close attachment causes a constriction in the condensed chromosome.
- c The period in the cell cycle when the cell is not dividing. During this phase, cellular metabolic activity is high, chromosomes and organelles are duplicated, and cell size may increase. often accounts for about 90% of the cell cycle.
- d A structure of proteins attached to the centromere that links each sister chromatid to the mitotic spindle.
- e A cell containing only one set of chromosomes (n).
5 Multiple choice questions
- specific location of a gene on a chromosome
- The pairing and physical connection of duplicated homologous chromosomes during prophase I of meiosis.
- A cell containing two sets of chromosomes (2n), one set inherited from each parent.
- A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei.
- 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.
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.
autosomes → A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei.
density dependent inhibition → 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.
S phase → The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
cell cycle → 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).
