The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
The connecting element between the pairs of strands that form the double helix of DNA is hydrogen bonds.
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.
If the strands of the double helix were parallel, the end would appear as two straight lines running side by side, rather than twisting around each other. This configuration would not allow for the hydrogen bonding between the bases that stabilize the structure of the double helix in its normal form.
The main difference between a right-handed alpha helix and a left-handed alpha helix in protein structures is the direction in which the helix twists. In a right-handed alpha helix, the helix twists in a clockwise direction, while in a left-handed alpha helix, the helix twists in a counterclockwise direction. This difference in twisting direction affects the overall shape and stability of the protein structure.
DNA is double stranded while RNA only has one strand.
DNA is double Helix But A Gene is a part of that double helix.
the difference is that DNA is a double helix and RNA is a single chain
double helix
The function of the double helix in normal DNA (B-Dna) is easy attachment of histosomes for folding of the DNA, and thus important in the creation of chromatids.
Helicase uses free energy from ATP to break the hydrogen bonds between the double helix of the DNA. It breaks the bonds between adenine and thymine, and guanine and cytosine. This unzips the double helix structure.

Double Helix :D
Generally hydrogen bonds between the different base pairs holds the double helix together.
