The Cell Cycle and Cell Division Questions and Answers 100% Solved

The Cell Cycle and Cell Division Questions and Answers 100% Solved Most cells in an organism go through a cycle of growth, development, and division called the _________________. cell cycle Because of the cell cycle, organisms grow and _________, replace old or damaged cells, and produce new cells. develop There are two main phases of the cell cycle- interphase and the ___________ phase. mitotic __________ is the period of growth and development for a cell. interphase During interphase, most cells go through three stages- rapid growth and ____________ of the organelles; replication of ___________, the genetic information in a cell; and preparation for ____________________. replication; DNA; cell division During the mitotic phase, a cell ____________________. reproduces ___________________ makes up most of the cell cycle. interphase During interphase, the DNA in the cell is called ________. chromatin Interphase begins with a period of rapid growth- the ___________ stage G1 During the ___________ stage of interphase, the cell replicates its strands of chromatin. S _________________ are the two identical strands of DNA that make up the duplicated chromosome. Sister chromatids The sister chromatids are held together by a structure called the _______________. centromere The final stage of interphase- the ______ stage- is a period of growth and final preparation for mitosis. G2 Before a cell divides, it makes copies of all its _________. organelles In _________, the nucleus and its contents divide. mitosis In ___________, the cytoplasm and its contents divide. cytokinesis Two new _________________ result from mitosis and cytokinesis. daughter cells During ____________, duplicated DNA condenses into chromosomes. prophase During ______________, the chromatids in each duplicated chromosome separate and are pulled in opposite directions by the spindle fibers. anaphase During _______________, sister chromatids in each duplicated chromosome separate and are pulled in opposite directions by the spindle fibers. anaphase During ______________, chromosomes begin to uncoil, and two new identical nuclei form. telophase After mitosis, _____________ usually divides a cell's cytoplasm, forming a new cell membrane around each daughter cell. cytokinesis In animal cells, a ____________ in the middle of the cell gets deeper until the cell _________________ comes together to divide the cell. furrow; membrane In plant cells, a ________________ grows outward toward a new cell wall until two new cells form. cell plate The cell cycle results in two new _____________ that are genetically identical to each other and to the original cell, which no longer exists. daughter cells The cell cycle is important for reproduction in some organisms, growth in ______________ organisms, replacement of worn-out or damaged cells, and repair of damaged cells. multicellular List the steps of the cell cycle 1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cytokinesis What are the the 2 parts of the mitotic phase? Mitosis and Cytokinesis What are the steps of mitosis? Prophase, Metaphase, Anaphase, and Telophase What are the 3 parts of Interphase? G1, S, and G2 Name which part of Interphase is a period of rapid growth and development G1 Name which part of Interphase includes DNA replication S Name which part of Interphase includes more growth and development, and preparation for cell division G2 -Copied DNA condenses into chromosomes -The nucleus disappears, and the nuclear membrane breaks down -Spindle fibers begin to form Which phase of mitosis is this? Prophase -Chromosomes line up in a single file at the middle of a cell Which phase of mitosis is this? Metaphase -Sister chromatids separate -Spindle fibers begin to shorten, pulling chromatids toward opposite sides of the cell -The cell begins to lengthen Which phase of mitosis is this? Anaphase -A nuclear membrane forms around the chromatin -Chromosomes begin to unwind -Spindle fibers begin to break down -Two identical nuclei form Which phase of mitosis is this? Telophase What is a centromere? (The central point of origin for the spindle fibers on either side of the cell that appears during cell division) Which part of the cell cycle takes up the most time? Interphase Which part of the cell cycle is the period during the cell cycle's growth and development? Interphase
