Two strands of DNA join together to form a double helix. These strands are composed of nucleotides, and they pair through complementary base pairing: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). The sugar-phosphate backbone of each strand runs in opposite directions, which is referred to as antiparallel orientation. This structure is fundamental to DNA's stability and its function in storing genetic information.

The area where the duplicated strands join is called the "replication fork." This is where the DNA helicase unwinds the DNA double helix, creating two single strands that serve as templates for the synthesis of new DNA strands.
The strands of the DNA ladder are made of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). These nucleotides join together to form the double helix structure of DNA.

Ligase is an enzyme that helps to join DNA fragments together by forming a strong bond between the sugar-phosphate backbone of the DNA strands. This process is essential for DNA replication, repair, and recombination.
The two strands are held together by Hydrogen bonds between the complementary base pairs (A to T and G to C). These bonds break, and the strands separate, when enough heat is added or the DNA is placed in an alkali environment.
DNA strands are held together by hydrogen bonds.
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
The DNA strands are held together by hydrogen bonds between complimentary base pairs.
Ligase uses ATP to help join together the ends of DNA strands during the process of DNA ligation. The ATP provides the energy needed for the enzyme to catalyze the formation of a phosphodiester bond between the DNA fragments, effectively sealing the strands together.
