Class teacher asked you to perform an experiment to prepare stained temporary mount of human cheek cells. He asked you to answer the following questions : (i) Name the stains you would use for staining scrap of inside of your cheek. (ii) Where would you see coloured spherical or oval dot-like structures in each cheek cell ? Name this structure.

In eukaryotes, the process of division of a somatic parent cell into two daughter cells is known as mitosis. During the M or mitosis phase of a cell cycle, the chromosomes present in the nucleus are separated into two identical sets, which eventually form two daughter nuclei. This is followed by cytokinesis. Onion root tips are most commonly used to observe the different stages of mitosis in the laboratory. Each onion cell contains a total of eight chromosomes. DNA specific stains are used to visualise these chromosomes in different phases of mitosis. Considering the number of chromosomes in an onion cell is 8, what would be the number of chromosomes in each daughter cell after mitosis ?

    Read the following extract carefully and rewrite it from the point of view of Rosalind : [You may begin with : One day I and Celea met Orlando ... ] One day she and Celia met Orlando. He did not recognize them because of their stained faces and simple clothes. He thought they were a shepherd boy and his sister. He made friends with them and often came to see them in their cottage. Rosalind, still dressed as Ganymede, one day made fun of Orlando's poetry. 'I' 11 cure you of your love for this girl Rosalind ! she said. I will pretend to be Rosalind and you shall make love to me.' And there followed an amusing scene, with Orlando calling Ganymede "Rosalind" and swearing that he would die of love for her, and Ganymede refusing to believe it. 'Men have died from time to time, and worms have eaten them, but not for love ! ' said Rosalind, laughing at the earnest Orlando. At last the young man said he would have to go. 'I must attend the Duke at dinner', he explained, 'but I shall be with you again at two o'clock.' So Rosalind said good-bye to him, and waited impatiently for his return. Two o'clock came, however, but no Orlando, and Rosalind began to feel angry and disappointed. Just then Oliver, Orlando's elder brother, came running through the forest to their cottage. He held a blood-stained handkerchief in his hand, which he gave to Rosalind, saying that Orlando had sent it to her. 'What has happened? What must we understand by this ?' cried Rosalind, full of fear for her lover's safety.
