Identify the locations of the N- and C-termini of StrepG. Indicate the orientation of the helical macrodipole, showing the (δ+) and (δ−) ends of the macrodipole.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
