What are the sides of the DNA ladder made of?
The sides of the DNA ladder are made of alternating deoxyribose sugar molecules and phosphate groups.
The DNA molecule has a double helix structure, resembling a twisted ladder. The sides, or rails, of this ladder are composed of two long chains of nucleotides running in opposite directions. Each nucleotide consists of three components: a deoxyribose sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). The deoxyribose sugar molecules and phosphate groups alternate to form the backbone of the DNA strand. The phosphate groups link the sugar molecules together through covalent bonds, creating a strong and stable structure.
The nitrogenous bases, which include adenine (A), thymine (T), cytosine (C), and guanine (G), project inward from the sugar-phosphate backbone and form complementary base pairs (A with T and C with G) between the two DNA strands. These base pairs are held together by hydrogen bonds, which provide the specificity and complementarity necessary for DNA replication and information storage. This elegant molecular architecture allows DNA to store and transmit genetic information accurately.
