    Which metal controls in the rate of neutrons in the nuclear reactor?

    The gene that controls the rate of mutation of another gene is :

    Respiration mechanism is controlled by

    Assertion :- Pneumotaxic centre can moderate the functions of the respiratory rhythm centre. Reason :- Neural signal from pneumotoxic centre can reduce the duration of inspiration and thereby the alter the respiratory centre

    Assertion :- In prokaryotes, control of the rate of transcriptional initiation is the predominant site for control of gene expression. Reason : The regulatory protein can act both positively (activators) & negatively (repressors)
