ll Verizon LTE 11:28 AM d21.arizona.edu 30%. Qvestion 10(1 point Which of the following accurately describes the events of the various phases of mitosis? O During metaphase, the spindle fibers contract, separating the sister chromatids During prometaphase, the nuclear envelope breaks down, and the spindle fibers attach to the chromosomes that will guide the chromosomes In prophase, the mitotic spindle begin to assemble In prophase, the DNA is replicated and begins to condense, and chromosomes become visible to the naked eye. Qvestion ( point If we compare mitosis to meiosis I, one difference is evident at telophase: in mitosis, each of the daughter nuclei are diploid; at telophase I of melosis, the nuclel are haploid one difference is at anaphase: in mitosis, homologous pairs separate; in meiosis I, it is sister chromatids that separate one difference is obvious at metaphase: in mitosis, the chromosomes line up single-file; in meiosis I they line up as pairs one difference is evident at telophase: in mitosis, each of the chromosomes consist of two sister chromatids (two DNA double-helices) O consists of one DNA double helix; at telophase I of meiosis, the chromosomes Question 12 (3 point Meiosis is the process that produces both eggs and sperm in mammals (such as humans); the process and the end-products are quite similar for both eggs and sperm: 4 functional haploid gametes. O True O False Qwestion 13 (1 point Melosis I1 is essentially the same as mitosis-with one important difference: the nuclei in meiosis II are haploid, while the nuclei in mitosis are diploid. O True O False Question 14 (1 point Melosis is different from mitosis in that O in meiosis, the daughter cells have half as many chromosome as the parent cell O in meiosis there are two rounds of nuclear division (instead of just one) O mitosis produced genetically unique daughter cells, unlke melosis O mitosis produces four daughter cells; melosis produces twoExplanation / Answer
Answer 10 In prophase, the mitotic spindle microtubules that will guide the chromosome begin to assemble.
The mitotic spindle is made of long proteins called microtubules that begin forming at opposite ends of the cell. The spindle will be responsible for separating the sister chromatids into two cells.
