Difference between Mitosis and Meiosis<\/strong><\/h3>\n
Mitosis and meiosis are two distinct processes of cellular division, each serving different purposes in the life cycle of cells. Here’s an overview of the key differences between mitosis and meiosis.<\/div>\n
What is Mitosis?<\/strong><\/h5>\n

It is the type of cell division, which makes sure the same variety of chromosomes<\/a> in the daughter cells as that in the parent cells. Despite small differences, the major steps of mitosis are mostly similar in both plants and animals. However, to prevent confusion our statement will be based upon the animal cell.<\/p>\n

The mitosis occurs in haploid as well as in diploid cells in nearly all parts of the body when needed. Mitosis is a continuous process; however, it can be divided into two phases, i.e., karyokinesis, which involves the division of the nucleus<\/a>, and cytokinesis which describes the division of the whole cell.<\/p>\n

What is Meiosis?<\/strong><\/h5>\n

Meiosis is a special kind of cellular division in which the number of chromosomes in daughter cells is reduced to half, as compared to the parent cell. In animals at the time of gamete formation, while in plants when spores are generated.<\/p>\n

\"Meiosis<\/p>\n

Each diploid cell after meiosis produces 4 haploid cells, because it involves two consecutive divisions after single replication of DNA. Two divisions are meiosis I and meiosis II. The initial meiotic division is the reduction division, whereas the second meiotic department is just like the mitosis.<\/p>\n

Frequently Asked Questions\u00a0<\/strong><\/h5>\n

Q1: What is cell cycle?<\/strong><\/p>\n

Ans:<\/strong> The cell goes through a sequence of changes that involve a period of growth, replication of DNA, followed by cell division is called the cell cycle.<\/p>\n

Q2: What is contractile ring?<\/strong><\/p>\n

Ans:<\/strong> A contracting belt of microfilaments are present in the middle of the cell. These microfilaments are called contractile ring.<\/p>\n

Q3: Is interphase a resting phase?<\/strong><\/p>\n

Ans:<\/strong> No, interphase is not a resting phase but misleadingly termed as resting phase. It is the phase of great biochemical activity.<\/p>\n

Q4: What are restriction points or check posts during cell cycle?<\/strong><\/p>\n

Ans:<\/strong> A checkpoint occurs late in the G1<\/sub> before entering the S phase. If all internal and external factors are favorable, the cell replicates its DNA and then it divides.<\/p>\n
