Is DNA a single strand of nucleotides?
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
How would you describe the structure dna?
DNA is a double-stranded molecule that resembles a twisted ladder, known as a double helix. It consists of four different nucleotide bases - adenine, thymine, cytosine, and guanine - that pair up in specific combinations. These base pairs provide the genetic instructions that determine an organism's traits and characteristics.
How many colors are in a DNA strand?
If you see a DNA strand with colors on it, it is only for visual purposes and is just a model. On the molecular level, there are no clear color-coordinated divisions between groups on the double helix.
The most accurate description of the structure of deoxyribonucleic acid is?
DNA is a double-stranded helical structure made up of nucleotides. Each nucleotide consists of a phosphate group, a sugar (deoxyribose), and one of four nitrogenous bases (adenine, thymine, guanine, or cytosine) that form base pairs (A-T and G-C) between the two strands. The helix has a twisted ladder-like appearance.
What four bases are in DNA?

What are the four nitrogen bases that make up the rungs of the double helix?
In DNA, the four bases are: adenine, guanine, thymine and cytosine.

How do you make a double helix model?
One way might be to get a flexible ladder and then turn both ends in opposite directions on its axis, in other words twist it. The result should be quite similar to a DNA double helix. You can use beads: http://www.instructables.com/id/The_Double_Helix_Glass_Bead_DNA_model/
What all does DNA contain?
It's made up in a "double helix" structure of four main chemicals, adenine, guanine, thymine, and cytosine. == ==

What are the restrictions on the pairing of the four different nucleotide bases in the double helix?
Adenine can only bond to thyamine and cynanine can only bond to guamine (A to T, C to G).
The structure of DNA was discovered by?
DNA has both primary and secondary structures, on a primary level it is made up of three main molecules a sugar and phosphate group backbone and attached to this backbone on of the four nitrogen bases. On a secondary level the sugar phosphate and necleotides run anti parallel to another strand of DNA and form a helical structure by wrapping around itself and is held together by hydrogen bonds.
What are three main difference between RNA and DNA?
DNA has a deoxyribose sugar; RNA has a ribose sugar DNA is a double stranded helix; RNA is a single stranded helix RNA has the nitrogen base uracil instead of thymine (thymine is one of the four bases in DNA).
What best describes the structure of DNA?

How many strands of nucleotides make up DNA double helix?
A DNA double helix is made up of two strands of nucleotides that are complementary to each other. Each strand consists of a sequence of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
