<p>Meiosis is significant as it leads to genetic variation. It differs from mitosis in that it involves two rounds of cell division, resulting in four non-identical daughter cells with half the chromosome number.</p> Signup and view all the answers

<p>Mitosis is a process of cell division that results in two genetically identical daughter cells. It involves prophase, metaphase, anaphase, and telophase.</p> Signup and view all the answers

<p>Centrioles/centrosome are involved in organizing the microtubules during cell division, contributing to the formation of the spindle fibers and ensuring proper chromosome separation.</p> Signup and view all the answers

<p>The Oparin-Haldane theory proposes that life originated from simple organic compounds in the primordial Earth's atmosphere, leading to the formation of complex organic molecules, and eventually, the first living cells.</p> Signup and view all the answers

<p>Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. Darwin's theory of evolution emphasizes variation, inheritance, selection, and time.</p> Signup and view all the answers

<p>The synaptonemal complex is a protein structure that forms between homologous chromosomes during prophase I of meiosis. Chiasma refers to the point where genetic exchange occurs between homologous chromosomes. Recombination is the process where genetic material is exchanged between homologous chromosomes. The metaphase plate is an imaginary plane in the cell where chromosomes align during metaphase.</p> Signup and view all the answers

<p>Meiotic prophase-I consists of five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. During these stages, events such as chromosome condensation, synapsis, crossing over, and chiasma formation occur.</p> Signup and view all the answers
