The coronavirus genome is approximately 30000 bases long. The bases are represented as rectangles with different heights. Sequence reads from left to right up to down and ends with the column does not fill up all the rows.

Height 1 = A adenine

Height 2 = T thymine* (U Uracil)

Height 3 = G guanine

Height 4 = C cytosine
