1. The "Cross"- and "Form"-coded amino acids:

Counting on 24 amino acids we get the same sums for G+C-coded and A+U-coded ams in 1st and 2nd base ordering. This implies that the ams changing position to the other group in both directions have the same mass or A-number sums, 385.
   Amino acids with these codons are here named Cross-coded and Form-coded ams.

385:

                 Row sums show the same number partition as the columns (+/-1):
                385 - 209 / 176.

In this arrangement we have the lighter ams in each pair of codons (differing only in 3rd base) on the first row, the heavier ones on the middle row.

About the 3rd base in the codons, note that

Row 1 has 3rd base = U / C, except Gln.
                                                   > a "pole exchange" in last step.*
Row 2 has 3rd base = A / G, except His.
Row 3 has only "2-base coded" ams, i. e. 3rd base indifferent.

*Cf. His the only ams not derived from stations in the glycolysis.

Number 11 - and factor 7 - dominates these groups:

Compare similarities of different number divisions:

B-chains = 12 x 74 -1  = 887 A
R-chains =                  = 770 A

N-sum R+B-chains     = 771 N
Z-sum R+B-chains      = 886 Z

Number 35 is the N-number of the unbound B-chains.

2.  Number 385 a random one?

a. 385 = 11 x 35 = 11 x [ 3³ + 2³ ] = 297 + 88
                                          ↓     ↓
                                          27 - 8
                                              ↓
                              interval 19, sum 35, times 11 = 209, 385

    Compare in the number chain 2x² of electron shells*:

               50 --- 32 --- 18 ---- 8 --- 2 --- 0:
                                     ↓        ↓
                               2 x 3² --- 2² x 2

*Charge versus Mass

b. 385 = the side in a square with the diagonal 544 (the A-number for G+C-coded ams, R):
                                           544 / √2 = 384,66.
