Double Helix Definition Biology Simple
Double Helix - Genome.gov
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups. More Information
Double Helix | Definition of Double Helix by Merriam-Webster
Double helix definition is - a helix or spiral consisting of two strands in the surface of a cylinder that coil around its axis; especially : the structural arrangement of DNA in space that consists of paired polynucleotide strands stabilized by cross-links between purine and pyrimidine bases.

What is a double helix simple definition? - AskingLot.com
In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure.

Double-Helix Structure of DNA - ThoughtCo
Double helix is the biological term that describes the overall structure of DNA. Its double helix consists of two spiral chains of DNA. This double helix shape is often visualized as a spiral staircase. The twisting of DNA is the result of both hydrophilic and hydrophobic interactions between the molecules that comprise DNA and water in a cell. More Information

Deoxyribonucleic Acid (DNA) Fact Sheet
So, if you know the sequence of the bases on one strand of a DNA double helix, it is a simple matter to figure out the sequence of bases on the other strand. DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA helix splits down the middle and becomes two single strands. More Information
