How do I add a DOM element with jQuery?

I have a funciton that I am currently using to show a hidden div.a_type

How can I modify this code so that instead of fading in the hidden div, I can add the new div to the DOM

jQuery(function(){   // Add Answer

    jQuery(".add_answer").click(function(){
      if(count >= "4"){
        alert('Only 4 Answers Allowed');
        }else{
      var count = $(this).attr("alt");
      count++;
      $(this).parents('div:first').find('.a_type_'+count+'').fadeIn();
      $(this).attr("alt", count);
    }

    }); 

});

Ok, now that i have this sorted out, i have one more question,

I have another function that removes the inserted div's if a button is clicked. It's not working now that the additional divs are not loaded into the dom on pageload. How can i trigger the function to remove these now?

jQuery(function(){ // Hide Answer

jQuery(".destroy_answer").click(function(){
  $(this).parents("div:first").fadeOut(function (){ $(this).remove() });
   var count = $(this).parents('div:first').parents('div:first').find('.add_answer').attr("alt");
   count--;
   $(this).parents('div:first').parents('div:first').find('.add_answer').attr("alt", count);

}); 

});
