5 Multiple choice questions
- A haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.
- A structure of proteins attached to the centromere that links each sister chromatid to the mitotic spindle.
- 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.
- The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.
- The reciprocal exchange of genetic material between nonsister chromatids during prophase I of meiosis.
5 True/False questions
density dependent inhibition → The phenomenon observed in normal animal cells that causes them to stop dividing when they come into contact with one another.
mitosis → 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.
asexual reproduction → 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.
genome → The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
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.
