The displayed segment is a part of a DNA MOLECULE. This nucleic acid (DNA) forms a double helix.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of nucleotides, which interact by hydrogen bonds.
Conversely, the ribonucleic acid (RNA) molecule is a single-stranded molecule consisting of a long chain of nucleotides.
In DNA, there are four types of nucleotides, each containing one distinct nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
According to the base pair rules, Adenine always pairs with Thymine via two hydrogen bonds, whereas Guanine pairs with Cytosine through three hydrogen bonds.
In RNA, Thymine bases are replaced by Uracil bases.
