In meiosis, DNA synthesis is followed by two subsequent rounds of chromosome segregation, leading to the formation of haploid gametes (see ). Hermaphrodites temporarily produce male gametes during the third larval stage, before switching to an oogenesis program. In adult animals, a proliferating stem-cell population at the distal end of each gonad arm forms precursor germ cells. These precursor cells go through S phase and enter a prolonged meiotic prophase, in which homologous chromosomes pair, synapse and undergo recombination in the pachytene stage. Oocytes complete development while in diakinesis, and undergo maturation when reaching the spermatheca. The oocyte pronucleus completes meiosis I and II upon fertilization. Meiosis is described elsewhere (see ).

Animal development from a single-cell zygote to fertile adult requires many rounds of cell division. During each division, cells complete an ordered series of events that collectively form the "cell cycle". This cycle includes accurate duplication of the genome during the DNA synthesis phase (), and segregation of complete sets of chromosomes to each of the daughter cells in (A). The somatic cell cycle also contains "ap" phases, known as , which connects the completion of M phase to initiation of S phase in the next cycle, and , which separates the S and M phases. Dependent on environmental and developmental signals, cells in G1 may temporarily or permanently leave the cell cycle and enter a quiescent or arrested phase known as .

Macromolecular Synthesis in Cells Infected by Frog …

Using fluorophenylalanine (FPA) to interfere with functional viral protein synthesis, we have investigated the complex transcriptional and post-transcriptional controls that operate in cells infected with frog virus 3. Our previous data, obtained by polyacrylamide gel electrophoresis of viral RNAs and proteins, showed that the addition of FPA at the beginning of infection completely prevented the synthesis of late viral RNAs and late viral proteins and blocked the normal progressive decline in the rates of synthesis of two quantitatively different classes (class I and class II) of early proteins. These results indicated that the initiation of late RNA and late protein syntheses, as well as the post-transcriptional regulation of early protein synthesis, was under the control of virus-specific proteins (D. B. Willis, R. Goorha, M. Miles, and A. Granoff, J. Virol. 24:326-342, 1977). In this communication, we show that the viral protein required to “turn on” the synthesis of late RNAs and late (class III) proteins was made within 1 to 1.5 h postinfection (p.i.); when we added FPA after this time, we observed the synthesis of all of the late macromolecules. The data also suggest that another viral protein, separate from the “turn-on” protein, controlled the abundance of late RNAs. In addition, at least two separate proteins were involved in the post-transcriptional regulation of two classes of early proteins. When FPA addition was delayed until 2 h p.i., the rate of synthesis of class I proteins (which normally peaked at 2 h p.i.) was reduced by 6 h p.i. just as in a normal infection, but the rate of synthesis of class II proteins (which normally reached a maximum at 4 h p.i. before declining) was reduced only when we waited until 3 or 4 h p.i. to add FPA. These experiments corroborate and extend previous evidence for the existence of numerous viral regulatory proteins in the control of frog virus 3 gene expression at the transcriptional and post-transcriptional levels.

The combination today, of the spiritual energies of these two complementary disciplines in the life of man will produce fully integrated human beings, and thus help to evolve a complete human civilisation, for which the world is ripe and waiting. This is the most outstanding contribution of Swami Vivekananda to human thought today. This synthetic vision of his finds lucid expression in a brief but comprehensive testament of his Vedantic conviction:

These alkaloid toxins are secreted by certain species of Colombian – so called because Indians in Western Colombia used their secretions to poison the tips of blow darts. The most poisonous frog, the bright yellow Phyllobates terribilis, secretes batrachotoxin at levels high enough to kill several people.
