His detailed drawings of the stages are the basis of the account still given in textbooks.

Interphase occupies more than ninety-five per cent of the duration of the cell cycle, because in it the cell must grow to a sufficient size, synthesise proteins and RNA, duplicate its entire DNA and prepare the structures needed for division.

This single difference is the reason meiosis I is called the reduction division. In anaphase I the two homologous chromosomes of each bivalent are pulled to opposite poles, but each of them still consists of two sister chromatids joined at an undivided centromere.

In the zygotene sub-stage of prophase I the two members of each pair of homologous chromosomes come to lie side by side along their whole length, matching point for point, and the structure that forms between them and holds them together is called the synaptonemal complex.

By this sub-stage the homologous chromosomes have already paired in zygotene and are held together as bivalents or tetrads, each made of four chromatids.

Meiosis begins with a single round of DNA replication and is then followed by two successive nuclear divisions. Meiosis I is the reduction division, in which homologous chromosomes separate and the two cells formed already carry half the parental chromosome number.

An animal cell divides its cytoplasm by a cleavage furrow, in which the plasma membrane is pulled inward around the middle until the cell is pinched into two.

Once the chromosomes are aligned on the metaphase plate and every kinetochore is attached to a spindle fibre, the centromere holding the two sister chromatids together splits.

In this stage the condensed chromosomes, each consisting of two sister chromatids, are moved by the spindle fibres until their centromeres lie in one plane across the middle of the cell, known as the metaphase plate or equatorial plate.

In mitosis each centromere splits in anaphase and one chromatid of every chromosome goes to each pole, so the two daughter cells receive exactly the same number of chromosomes as the parent cell had, and exactly the same genetic information.

During this phase the DNA of the cell is copied so that the amount of DNA in the nucleus doubles, while the number of chromosomes remains unchanged because each chromosome now simply consists of two identical sister chromatids joined at the centromere.

The Union Home Secretary said the National School of Drama would present its programme with an array of around 2,000 artists drawn from 126 districts of the country that had at some point witnessed the menace of armed Naxalism, and that these artists would show through their performances what they…

The Union Home Secretary said that the play, curated by the National School of Drama and staged before the Prime Minister, takes Anandamath as its theme this year because it is the year of Vande Mataram, and that it rests on the novel's enduring idea that every Indian carries a…

The Union Home Secretary said the theme of the cultural items at the Rashtriya Ekta Diwas celebrations, the tableaux included, is Vande Mataram, and that this is its 150th year, from which several new features of the parade have been drawn.

Her point was the opposite in spirit: art should not be confined to galleries but should also travel to schools, universities, public spaces and wider sections of society, which makes option C a statement she did make.

Besides giving away the Lalit Kala Akademi Awards to the artists of the 65th National Exhibition of Art, the President felicitated the Grand Prize winners and the artists who received Honourable Mentions at the third edition of the Print Biennale India, which is the Akademi's platform devoted to printmaking.

President Droupadi Murmu handed over the Lalit Kala Akademi Awards to the artists selected for the 65th National Exhibition of Art at a ceremony in New Delhi, and at the same function she felicitated the Grand Prize winners and the Honourable Mentions of the third Print Biennale India.

Under Article 243F, the minimum age to become a member of a Panchayat is 21 years, not 25. Part IX of the Constitution, added by the 73rd Amendment Act, 1992 and in force from 24 April 1993, lays down the framework of Panchayati Raj.

That law only restrained child marriage by punishing those who performed it; the Prohibition of Child Marriage Act, 2006 goes further, making such a marriage voidable at the option of the contracting party who was a child, providing for Child Marriage Prohibition Officers and injunctions, and keeping the legal age…

The Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act, 1989 came into force on 30 January 1990. It defines a long list of specific atrocities, provides for Special Courts and Special Public Prosecutors, requires relief and rehabilitation for victims, and bars anticipatory bail for the offences it creates.
