- cell cycle
- asexual reproduction
- a 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.
- b 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.
- c 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.
- d 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).
- e The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
5 Multiple choice questions
- The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.
- A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants and some algae.
- A cell containing only one set of chromosomes (n).
- The X-shaped, microscopically visible region where crossing over has occurred earlier in prophase I between homologous nonsister chromatids. they become visible after synapsis ends, with the two homologs remaining associated due to sister chromatid cohesion.
- 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.
5 True/False questions
diploid → A cell containing two sets of chromosomes (2n), one set inherited from each parent.
chromatin → The X-shaped, microscopically visible region where crossing over has occurred earlier in prophase I between homologous nonsister chromatids. they become visible after synapsis ends, with the two homologs remaining associated due to sister chromatid cohesion.
gametes → The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
meiosis → 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.
autosomes → A chromosome that is not directly involved in determining sex; not a sex chromosome.
