On the motion of either the state or the defendant or on its own motion, the court shall cause the jurors to be asked severally if the verdict rendered is their verdict. If a juror dissents, the court must direct that the jury be sent back for further consideration. If there is no dissent the verdict shall be entered of record and the jurors discharged. However, no motion to poll the jury shall be entertained after the jury is discharged or the verdict recorded.
