The binding specificity of different E-boxes is found to be essential in their function. E-boxes with different functions have a different number and type of binding factor. The consensus sequence of the E-box is usually CANNTG; however, there exist other E-boxes of similar sequences called noncanonical E-boxes.
The more common sizes of cookie sheets are tagged as Full, Three Quarters, Half and Quarter. For âHow big is a cookie sheet?â in the Full-size variety, this one measures approximately 26 inches in width by 18 inches in depth and about an inch thick.
The rectangular pan that most home bakers are familiar with (and that 1 box of Duncan Hines, Betty Crocker or Pillsbury cake mix will make one of) is the quarter sheet pan, which measures 13x9, with a depth of either 2 or 3 inches. If you laid 4 of these pans together, this would be approx. the size of a full sheet. Hopefully the chart below will answer your other questions. Pan name measurement # of 2-inch 2-inch party servings. Quarter sheet 13-inches x 9-inches 20. Half sheet 12-inches x 18-inches 40. 3/4 sheet 18-inches x 18-inches 60. Full sheet 18-inches x 30-inches 80. Hope this helps.
