#2690: Cool S explain

[10 drawings evolving from simple dashes, to a “cool S” symbol, to a representation of DNA. Unless otherwise stated, each drawing adds to the previous drawing]

First drawing - three vertical lines side by side over three equally sized vertical lines

Second drawing - Two diagonal lines added from the bottom of the top left line to the top of the bottom middle line, and the bottom of the top middle line to the top of the bottom right line

Third drawing - Four diagonal lines added from the top of the top left line and top right line, and the bottom of the bottom right line and bottom left line. The two lines at the top meet above the top middle line, at a 90 degree angle. The two lines at the bottom meet below the bottom middle line, at a 90 degree angle, making an incomplete “Cool S”, missing two lines.

Fourth drawing - Two diagonal lines added. One from top of the bottom left line, pointing towards the bottom of the top middle line; it stops halfway where it intersects with the line between the top of the bottom middle line and the bottom of the top left line drawn in the second drawing. One from bottom of the top right line, pointing towards the top of the bottom middle line; it stops halfway where it intersects with the line between the bottom of the top middle line and the top of the bottom right line drawn in the second drawing. forming a complete “Cool S”

Fifth drawing - Resets the last few steps and is the same as the second drawing.

Sixth drawing (located under the first drawing, making a new line of drawings) - The lines from the fifth drawing remain present and untouched, but there are now three vertical lines side by side above and below, with a gap left between them and the previous lines.

Seventh drawing - The pattern between the middle two sets of three lines established in the second drawing is repeated above and below, such that for each pair of three lines, Two diagonal lines are added from the bottom of the top left line to the top of the bottom middle line, and from the bottom of the top middle line to the top of the bottom right line

Eighth drawing - The pattern between the middle two sets of three lines established in the fourth drawing is both reimplemented, and repeated in the upper and lower two sets of lines. One from top of the bottom left line, pointing towards the bottom of the top middle line; it stops halfway where it intersects with the line between the top of the bottom middle line and the bottom of the top left line drawn in the second drawing. One from bottom of the top right line, pointing towards the top of the bottom middle line; it stops halfway where it intersects with the line between the bottom of the top middle line and the top of the bottom right line drawn in the second drawing.

Ninth drawing - The same pattern as in the eight drawing, but with dots in some sections of the pattern.

Tenth drawing - The same pattern as in the ninth drawing, but the pattern is spaced out in halves. The dots have turned into lines, creating something comparable to DNA.

The structure of DNA was originally discovered by a group of especially cool middle school researchers.
