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.
Give the genetic content © and chromosome number (n) of a diploid cell during the following phases: a. G1 b. S-phase c. G2 d. metaphase e. anaphase f. telophase after cytokinesis
A parent cell divides to form two genetically identical daughter cells in the process of mitosis. For mitosis to take place:
A.
the parent cell must divide its DNA in half so each daughter cell gets only the genes needed to carry out its functions. In this way, differentiation occurs.
B.
the parent cell must reproduce its DNA during telophase
C.
the parent cell must first be fertilized
D.
the parent cell must replicate its entire genome prior to mitosis
E.
crossover must be delayed until the second cell division

- A Biology 30 student is describing, to a friend, the differences between mitosis and meiosis. She highlights the following characteristics of these processes. For each statement state if it's refering to mitosis, meiosis, mitosis and meiosis or neither. A. involves two rounds of cell division B. results in daughter cells that are identical to the parent cell C. creates gametes D. happens only in certain kinds of cells in the body E. happens more often in somatic cells, such as stomach lining cells, than in nerve cells, such as brain cells F. involves duplication of genetic materialarrow_forwardEven though the processes are very similar, mitosis and meiosis are two very distinct processes. What is the difference between meiosis and mitosis? a. Mitosis results in two identical sister cells genetically identical to the original parent cell, while meiosis also starts with diploid but results in haploid cells. b. Mitosis only occurs in plants and single cell organisms, while meiosis only occurs in animals. c. Mitosis starts with diploid but results in haploid cells, while meiosis results in two identical sister cells genetically identical to the original parent cell.arrow_forwardIn a comparison of the stages of meiosis to the stages of mitosis, which stages are unique ... to meiosis and which stages have the same events in both meiosis and mitosis?arrow_forward
