DNA, okay. I understand.
Differing from the subject, how is near Christmas in the United States, or at least where you are? Here, instead of snow men, we are building sand men! The temperature is really hot. In fact, last weekend is the hottest in December for 60 years! Other than weather, there are plenty of festivities and activities, and we just put up our Christmas tree. It looks professional, because of the planning. The larger ornaments are positioned at the bottom of the tree, the medium ones in the centre and the small ones at the top. After that, the other fancy-shaped ornaments are positioned anywhere.
