Which of the following is one of the very importantdifferences between mitosis and meiosis?a. Chromosomes align midway between spindle polesonly in meiosis.b. Homologous chromosomes separate only inmeiosis.c. DNA is replicated before mitosis only.d. Sister chromatids separate only in meiosis.e. Interphase occurs only in mitosis.
a. Explain how mitosis and meiosis are similar in their processes or mechanism using
two examples.
b. Explain how mitosis and meiosis are different in their processes or mechanism
using two examples.
**Please stay away from superficial statements such as both are a type of cell
division. We are asking for a more detailed example based on how the cells proceed
through the processes which has been highlighted in discussions, videos, and
readings.
For the following events, specify whether they occur during mitosis, meiosis I, or meiosis II:A. Separation of conjoined chromatids within a pair of sisterchromatidsB. Pairing of homologous chromosomesC. Alignment of chromatids along the metaphase plateD. Attachment of sister chromatids to both poles
