Question

Division of nucleus is indirect in
A. Mitosis
B. Budding
C. Binary fission
D. Fragmentation

Answer 1

Hint: Mitosis and meiosis are two kinds of nuclear division. Nuclear division is a part of cell division which is followed by cytokinesis. During cell division, nuclear division is the most important step which occurs in both mitosis and meiosis. Mitosis divides the nucleus in which both daughter cells are genetically identical. Whereas in meiosis, there is a reduction division which produces daughter cells that contain half of the genetic information from the parent cell.

Complete answer:
The process of nuclear division also known as Karyokinesis is the process in which nucleus elongates and a constriction appears at the center which further results in a dumb-bell shaped structure. Afterwards, the constriction deepens and the nucleus gets divided into two halves.
Mitosis or the mitotic division is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. This process usually occurs in vegetative or somatic cells, hence known as somatic division. Mitosis occurs in meristematic tissues like shoot and root tip. The process of mitosis results in the increase of size, shape and volume of plant parts which causes overall growth. The pattern of mitosis is similar in all of the cells.
In mitosis, the sister chromatids are separated into two new cells with exactly the same number of chromosomes and half the amount of nuclear DNA, hence it is also called equational division. Mitosis is an elaborate process involving a series of important changes in the nucleus as well as cytoplasm, hence it is also known as indirect division. In the mitotic division all necessary cytoplasm constituents and organelles as well as the chromosomes are precisely divided between the two daughter cells. Chromosome number does not change in mitosis. In all types of cells: haploid, diploid or polyploid, the process of mitosis is observed.

Hence option A.Mitosis is the correct answer

Note:
The four phases of mitosis are: prophase, metaphase, anaphase, and telophase. One of the major purposes of mitosis is for growth and replacing worn out cells in an organism. During cell division, the nuclear envelope breaks down but reforms again after the two cells separate. During the processes of mitosis and meiosis, chromatids are pulled to opposite ends by a structure known as spindle.
