Based on the nearest-neighbor model

G0 = G0INT + G0SYM + G0NN + nTERM-AU GTERM-AU, use the following parameters:

G0INIT = 4.09 kcal/mol G0SYM = 0.43 kcal/mol G0TERM-AU = 0.45 kcal/mol

to predict free energy change for forming RNA duplex from each of the following nucleic acid sequences:

(a) 5 ACGCA 3 (b) 5 GCUCG 3

(c) 5 ACUGUCA 3 (d) 5 GACUCAG 3
