Purine Composition of a DNA/RNA sequence
y = btd_purinecomp(x)
String of single-letter codes specifying a DNA/RNA sequence
Percentage composition of adenine and guanine bases (as a string)
y = btd_purinecomp(x)
calulates composition of a purine in DNA
sequence,that is number of A and G.
--> y = btd_purinecomp("ATCGATCGATCGTATATGCTAGCTA") y = 48 %
