- S phase
- a The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.
- b A display of the chromosome pairs of a cell arranged by size and shape.
- c 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.
- d The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
- e 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.

- A haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.
- The pairing and physical connection of duplicated homologous chromosomes during prophase I of meiosis.

5 True/False Questions
gametophyte → In organisms (plants and some algae) that have alternation of generations, the multicellular diploid form that results from the union of gametes. it produces haploid spores by meiosis that develop into gametophytes.
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.
sporophyte → 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.
G2 phase → The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.
gene locus → specific location of a gene on a chromosome
