The antiparallel relationship of the two strands of DNA refers to the
A) twisted configuration of the strands.
B) alternative branching pattern of the strands.
C) alignment of the strands,such that one strand starts with a 3' carbon and the other starts with a 5' carbon.
D) view at one end of the molecule-one strand has an A wherever the other has a T,and one has a G wherever the other has a C.
E) the different number of bonds between A and T versus G and C.

The antiparallel relationship of the two strands of DNA refers to the alignment of the strands, such that one strand starts with a 3' carbon and the other starts with a 5' carbon. This arrangement creates two grooves in the DNA molecule, the major and minor grooves, which are important for protein-DNA interactions. The other choices describe other aspects of DNA structure but do not specifically relate to the antiparallel nature of the two strands.
