Step-by-step explanation:
In DNA, the complementary base pairing rules specify that adenine (A) binds with thymine (T), and guanine (G) binds with cytosine (C). Therefore, the single-stranded DNA molecule that will bind in a complementary fashion to another single-stranded DNA molecule can be determined by pairing the appropriate bases.
For example, let's consider a sequence of bases in a single-stranded DNA molecule:
Original Strand: A T C G
To find the complementary single-stranded DNA molecule, we use the base pairing rules:
Complementary Strand: T A G C
Each base in the original strand pairs with its complementary base in the new strand. Adenine (A) pairs with thymine (T), thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C).
So, the single-stranded DNA molecule with the sequence "T A G C" will bind in a complementary fashion to the original single-stranded DNA molecule with the sequence "A T C G."
