- G1 phase
- binary fission
- a 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.
- b The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.
- 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 chromosome that is not directly involved in determining sex; not a sex chromosome.
- e 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 Multiple choice questions
- The reciprocal exchange of genetic material between nonsister chromatids during prophase I of meiosis.
- The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
- The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
- A modified type of cell division in sexually reproducing organisms consisting of two rounds of cell division but only one round of DNA replication. It results in cells with half the number of chromosome sets as the original cell.
- specific location of a gene on a chromosome
5 True/False questions
G2 phase → The second gap, or growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.
chiasmata → 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.
haploid → A cell containing two sets of chromosomes (2n), one set inherited from each parent.
synapsis → The pairing and physical connection of duplicated homologous chromosomes during prophase I of meiosis.
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).
