Yes, because each of the four nucleotide bases present in DNA have a corresponding base: adenine bases always pair with thymine bases, and cytosine bases always pair with guanine bases. For example, if one strand of a DNA molecule was CTAGGT, the sequence of the second strand would be, from left to right, GATCCA.
Sometimes, the dark spots on the marshmallow can fall off of the marshmallow. This means that, the system does not need to include the pieces that fell when determining the mass before and after.
