ポリソームのような舟橋から友禅流し
A scene of Yuzen Nagashi (a process of washing kimono silks) at a pontoon bridge over a river. This bridge actually illustrates the way a number of ribosomes (boats) are attached in a row along a single mRNA chain (a bridge) to translate in parallel, and then form a polysome. There is a grove, which is like a poly-A tail, extending from the bridge to the opposite bank of the river. The pieces of fabric form polypeptide chains synthesized by ribosomes with their edges trimmed in the shape of 'M' that is the abbreviation of methionine. Now, the translation processes probably have just terminated at the boats on the far end. The fabric is being folded while it is released from those boats.

ヌクレオソーム似のかっぽれ踊りが練り歩く
A parade of “Kappore”, a dance with “nigaigasa” or double layer umbrellas. A decorative piece of cloth modeled after DNA wraps around each umbrella approximately 2 times to link one umbrella to the adjacent umbrellas. This seems to be a replication of the “beads-on-a-string” structure consisting of a DNA strand and nucleosome cores. Those who hold the “nigaigasa” are men representing the four families of core histones. If you look closely, you can find a towel printed “a-ce” on its tail hanging from one of the men's waist. This looks like the acetylation of a tail of one of the core histones. It has been found that the initiation of transcription is related to histone acetylation. If that is the case, this towel may be a sign to start dancing.
