Detailed explanation-1: -There are two kinds of DNAs, single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). Accordingly, the DNA binding proteins usually consist of single-stranded DNA-binding proteins (SSBs) and double-stranded DNA-binding proteins (DSBs).
Detailed explanation-2: -The statement that is not true about DNA is that DNA contains adenine, guanine, cytosine, and uracil. So, the correct option is (e).
Detailed explanation-3: -DNA exists in a double-stranded form whereas RNA is mainly a single stranded molecule.
Detailed explanation-4: -Whereas DNA always occurs in cells as a double-stranded helix, RNA is single-stranded. RNA chains therefore fold up into a variety of shapes, just as a polypeptide chain folds up to form the final shape of a protein (Figure 6-6).
