Each half of the DNA strand. Why is DNA called the double helix?
DNA is called a double-helix because it consists of two strands that spiral around each other. A spiral shape is also called a helix, and there're two of them, so it's a double-helix.
What are the two long chains in the DNA called?
helix
How do you describe the basic structure of the DNA molecules?
DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.
How many DNA strands do have in most cells?
DNA consists of two strands of nucleotides twisted into a double helix.
When DNA replication occurs the enzyme which separates the two side of the helix is called?
Helicase
What are the two sides of the DNA helix held together by?
Hydrogen bonds.
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds
Which best describes the structure of a DNA molecule-?
a double helix- apex
What is the shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure and held together by hydrogen bonds between the bases?
double helix
Did the Watson and Crick model of DNA say two strands of the helix were held together by covalent bonds?
Not covalent, hydrogen-bonds.
What holds the two halves of a DNA double helix together?
Its Hydrogen Bonds that hold the two strands of the DNA double helix together.

What is the scientific term for the shape of the DNA strand?
The name of the shape of DNA is called double helix. There are two long strands of DNA connected in several points. These strands twist and look like a spiral or a spring.
What are the two long chains in the DNA called?
helix

The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.
What is Watson and Crick's DNA model?
DNA is a double helix made of two strands linked together with hydrogen bonds.
What is the moleculer shape of dna?
DNA molecule is shaped like a spiral staircase and is composed of two parallel strands of linked subunits.
