DNA is a chemical, the initials stand for deoxyribonucleic acid. It can form a variety of structures, but in the chromosomes it takes on the interesting structure of the double helix (two helices winding together in opposite directions). These helices form long strands which are then folded up into tangles, in the cell nucleus. It's not very neat, but it works anyway.

DNA is a double-stranded molecule made up of nucleotides, which are composed of a sugar molecule, a phosphate group, and a nitrogenous base. The nucleotide bases (adenine, thymine, cytosine, and guanine) pair up in a complimentary manner, with adenine pairing with thymine and cytosine pairing with guanine, to form the double helix structure of DNA. This arrangement allows DNA to store genetic information in the sequence of its bases.

DNA is made of nucleotides which are composed of?
DNA is made of nucleotides composed of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). These nucleotides are arranged in a double helix structure forming the DNA molecule.
What does NOT describe the structure of DNA?
Non-descriptive examples of the structure of DNA would include being composed of lipids, being a single helix, or having a variable number of nucleotides.
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 strands is DNA milecule made up of?
DNA molecule is made up of two strands that are arranged in a double helix structure. Each strand is comprised of a sequence of nucleotides that contain genetic information.
What is a structure made mostly of DNA molecules?
A chromosome is a structure made mostly of DNA molecules. Chromosomes are found in the nucleus of cells and contain genes that carry hereditary information.
what Describe the structure of the DNA molecule?
a DNA molecule is made up of a phosphate, sugar and base A double Helix Strand
What is the structure of DNA like?
nucleic acid arranged in a double helix
How did Watson and crick describe the structure DNA?
it was in strands
Which best describe the structure of DNA?
DNA has a double helix structure consisting of two strands made up of nucleotides that are connected by hydrogen bonds. The nucleotides contain a phosphate group, a sugar molecule, and a nitrogenous base (adenine, thymine, cytosine, or guanine). This structure allows for the genetic information to be stored within the sequence of the nitrogenous bases.
How is DNA molecule arranged?
DNA molecules are arranged by genetics
What are chains of chemicals arranged like rungs on a twisting ladder?
DNA molecules consist of chains of nucleotides arranged like rungs on a twisting ladder, forming the double helix structure. The nucleotides in DNA are made up of a phosphate group, a sugar molecule, and a nitrogenous base. The arrangement of these nucleotides determines the genetic information stored in the DNA molecule.
DNA is made of nucleotides which are composed of?
DNA is made of nucleotides composed of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). These nucleotides are arranged in a double helix structure forming the DNA molecule.
Is the sides of the DNA molecule are made up of repeating nitrogen bases and sugars?
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
What is the term used to describe the natural shape of DNA?
The term used to describe the natural shape of DNA is "double helix." DNA is made up of two strands that twist around each other in a spiral ladder-like structure, forming the double helix shape.
What chromosomes can be describe as?
Chromosomes are an organized structure of DNA and protein that is found in cells.
The DNA molecule is usually made up of how many strands?
The DNA molecule is typically made up of two strands that are arranged in a double helix structure. Each strand consists of a series of nucleotides that pair up based on complementary base pairing (A with T, C with G).
What does NOT describe the structure of DNA?
Non-descriptive examples of the structure of DNA would include being composed of lipids, being a single helix, or having a variable number of nucleotides.
