View the animation below, then complete the quiz to test your knowledge of the concept. These three stages are necessary for reproduction: the genetic material must be copied, the genetic material must be spatially separated, and only then can cell division occur. Finally, cytokinesis, the actual production of two different cells occurs during telophase. The segregation of DNA into two identical genomes begins in prophase and is completed by the end of anaphase. The copying of DNA occurs during the S phase. Reproduction occurs in steps at different times in the cell cycle. Telophase: Telephase begins once the chromosomes have completed separating. Chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their. The M phase is broken down into 4 sub-phases: Prophase, Metaphase, Anaphase. During interphase, cells are primarily involved with growth and maintenance during the G1 and G2 stages. prophase, metaphase, anaphase and telophase. Individual cells exhibit all of these properties as they go through the cell cycle. How Cells Divide How the Cell Cycle Works How is the cell cycle related to the primary functions of life? Living things have the following properties: they reproduce, they maintain themselves (homeostasis), and they grow. Which metal in the list is most reactive?ĭ.Biology, Eighth Edition (Raven) Chapter 10: The Prophase of Meiosis is quite long and more complex than the Prophase of Mitosis. The chromosomes are pulled apart by a mitotic spindle, which is a specialized structure consisting of microtubules. Which metal ion in the list is most difficult to reduce?Ĭ. Prophase, Metaphase, Anaphase, and Telophase Mitosis The process by which a eukaryotic cell separates the nuclear DNA and chromosomes and divides into two different but similar sets of nuclei is known as mitosis. Which metal in the list is the best reducing agent?ī. Cytokinesis is the final physical cell division that follows telophase, and is. Refer to the list of electrode potentials below to answer parts a to d.Ī g + ( a q ) + e − ⇌ A g ( s ) voltage = + 0.80 V C o 2 + ( a q ) + 2 e − ⇌ C o ( s ) voltage = − 0.28 V C u 2 + ( a q ) + 2 e − ⇌ C u ( s ) voltage = + 0.34 V P b 2 + ( a q ) + 2 e − ⇌ P b ( s ) voltage = − 0.13 V Z n 2 + ( a q ) + 2 e − ⇌ Z n ( s ) voltage = − 0.76 V \beginĪg + ( aq ) + e − ⇌ Ag ( s ) Co 2 + ( aq ) + 2 e − ⇌ Co ( s ) Cu 2 + ( aq ) + 2 e − ⇌ Cu ( s ) Pb 2 + ( aq ) + 2 e − ⇌ Pb ( s ) Zn 2 + ( aq ) + 2 e − ⇌ Zn ( s ) voltage = + 0.80 V voltage = − 0.28 V voltage = + 0.34 V voltage = − 0.13 V voltage = − 0.76 V Ī. These phases are prophase, prometaphase, metaphase, anaphase, and telophase. select the exception.ĭ) telophase c) interphase a duplicated chromosome has _ chromatidsĭ) four b) two the chromosomes have arrived at opposite poles duringĭ) prophase d) prophase the nuclear envelope begins to break up in lateĭ) prophase d) prophase DNA replication occursĭ) during prophase a) during S phase during the G2 phase of the cell cycle, most of the cell's activity is directed towardĭ) making the proteins that drive mitosis d) making the proteins that drive mitosis in which of the stages below are the chromosomes present as attached sister chromatids?ĭ) 1, 2, and 3 b) 1 and 3 which cell structure is present during plant cell division but not animal cell division?ĭ) cell plate d) cell plate checkpoint genes encoding proteins that promote mitosis are calledĭ) mitogens c) proto-oncogenes what is a noncoding, repetitive DNA sequence at the end of chromosomes?ĭ) telomerase a) telomere the sister chromatids detach from one another and become visibly separated chromosomes duringĭ) metaphase a) anaphase after mitosis, the chromosome number of a descendant cell is _ the parent's cellĭ) doubled compared to a) the same as if a cell's DNA is damaged, the products of _ genes interact to advance, delay, or stop the cell cycle.ĭ) onco a) checkpoint the spindle becomes visible during select the exception.ĭ) S c) R 3 of the 4 answers listed below are stages of actual nuclear division. a) starts when cell plate forms to eventually become the cell wall the spindle is made ofĭ) golgi bodies b) microtubules the distribution of cytoplasm to daughter cells is accomplished duringĭ) prokaryotic fission c) cytokinesis 3 of the 4 answers listed below are periods of the cell cycle.
