It has two, the reason being is that it has to form into the famous "twisting" pose.

What best describes the structure of a DNA molecule?
A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.
The structure of DNA is described as a?
Double helix - with a deoxyribose (sugar) and phosphate backbone, and nitrogenous bases in the centre.
Does DNA have bases on the interior of the double helix?
Yes. Indeed, while the Exterior of DNA is the sugar-phosphate backbone, the Interior of the DNA double-helix is where the [nucleotide] bases reside.
A DNA molecule is shaped like a?
A basic DNA molecule has three components - a ribose sugar, a phosphate chain and the base. Essentially, the sugar looks like a pentagon, the phosphate is a elongated chain with three phosphate groups and the base can be highly variable - either a purine or a pyrimidine. As the DNA molecule is built up, the backbone of DNA is created via the phosphate and ribose sugar linkages, and the genetic information is stored through the matching of the bases.
What is the role of sugar phosphate in DNA?
As the phosphate group has a negative repulsion due to the negative charge on oxygen it cause the DNA to bent to the double helix "spiral" structure as we know it - by Matouš Janda
The long backbones of the DNA molecules are made of alternating sugar and?
The sugar-phosphate backbones are the double helix staircase railings.
The sugar-phosphate backbones of the DNA double helix are oriented in opposite directions?
look in your book
The sugar-phosphate backbones of the DNA double helix are oriendted in opposite directions this commonly referred to at the?
Antiparallel
A double helix looks like a twisted ladderwhich parts of a twisted ladder are analogoius to the hydrogen bonds and sugar-phosphate backbones if a double helix of DNA?
vagina
Which part of the twisted ladder are analogous to the hydrogen bonds and sugar phosphate backbones of a double helix of DNA?
The Nucleotides and the hydrogen bonds.
What is the sugar-phosphate supporting structure of the DNA double helix is called?
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
What best describes the structure of a DNA molecule?

What best describes the structure of DNA molecule?
A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.
What are sides of a double helix made of?
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
What molecules form the sides of the double helix?
Phosphate and sugar.
What makes up the sides of a double helix?
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
Which best describe the structure of DNA?
(Apex) Sugar-phosphate backbones with bases on the inside.
