This is a period of intense synthesis and growth in the cell. The cell produces many materials required for its own growth and activities. The genetic material DNA replicates during interphas..

Miller, Skoog (1955) observed that 2 substances were effective in enhancing the growth of mature plant cells and tissues in culture. The two substances were coconut milk and degraded samples of yeast DNA. The active ingredient in both was found to be - furfuryl amino purine a mo..

These chromosomes occur in the oocytes (germcells in the ovary) of amphibians and in some insects. They are extremely large synapsed homologous chromosomes which can be seen in the diplotene stage of prophase-I in meiosis. They measure about 1500 to 2000 in length. A lampbrush chromosome consist..

One GTP is hydrolysed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolysed to AMP during amino acid activation. Thus, the formation of each pe..
