• What is the need of DNA intermediates in viral life cycle?

    RNA is enough for the synthesis of proteins. still RNA viruses do form DNA intermediates. what is the need of these intermediates to get integrated into the host genome? same question arises for lysogenic life cycle...why? why do viral DNA should integrate into host genome?

  • Which of the following statements correctly describes some aspect of protein disposal from prokaryotic cells?

    Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane... show more
    Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell. The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes.

  • How can this be right?!?

    MCAT QUESTION. In human females mitotic divisions of oogonia that lead to formation of presumptive egg cells (primary oocytes) occur between. The answer is Fertilization and Birth Only. How can this be right? By the time the sperm has fertilized the egg (fertilization) there is no more primary occyte it is by this time secondary?! Can anyone... show more
