Direct link to Ivana - Science trainee's post Interphase _is_ stage of , Posted 6 years ago. Yeast cells use RNA interference, while roundworms and some insects allow the formation of a diffuse structure along the entire chromosome. This system is preferred among organisms that reproduce sexually because it makes the population varied and genetically robust. 3. Sister chromatids stay together. You can find out more about our use, change your default settings, and withdraw your consent at any time with effect for the future by visiting Cookies Settings, which can also be found in the footer of the site. Sister Chromatids in Meiosis. 2. 32 4. 2. meiosis I 4. through the transcription of DNA to RNA, Human gametes are produced by _____. Each is now its own chromosome. Direct link to sinm9897's post What would happen in anap, Posted 4 years ago. 4. separation of sister chromatids, Measurements of the amount of DNA per nucleus were taken on a large number of cells from a growing fungus. The spots where crossovers happen are more or less random, leading to the formation of new, "remixed" chromosomes with unique combinations of alleles. Expert Answer. 4. anaphase I. "Sister Chromatids. Which of the following processes best describes the mechanism of gamete production in plants? A separated sister chromatid becomes known as daughter chromosome and is considered a full chromosomeMeiosis: Homologous chromosomes migrate toward opposite poles of the cell during anaphase I. Bailey, Regina. During which of the following phases of meiosis do centromeres split and sister chromatids migrate to opposite poles of the cell? Which diagram represents anaphase II of meiosis? During anaphase, sister chromatids separate and the centromeres divide.The sister chromatids are pulled apart by the shortening of the spindle fibers. How does natural selection apply to sexual reproduction as opposed to asexual reproduction? 4. a karyotype, Asexual reproduction occurs during which of the following processes? Telophase II Mitosis vs. Meiosis. The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis . The two identical chromosomes that result from DNA replication are referred to as sister chromatids. . Which statement is correct? Different between karyogenisis and dikaryogenesis. Select all that apply. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid. Minor alpha thalassemia 3.
