DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. It carries the genetic instructions that determine the biological development of an organism. There are two key properties that define DNA:
Double Helix Structure: DNA is made up of two strands that coil around each other in a shape known as a double helix. This twisted ladder-like structure is essential for DNA replication and protein synthesis. The sides of the ladder are made of sugar-phosphate backbones, while the rungs of the ladder are formed by complementary pairs of nitrogenous bases.

Explain the properties of DNA according to the Watson-Crick model?
Based on the Watson-crick model, a DNA molecule has two twisting strands of paired nucleotides. This allows the RNA to pair up as well, to transcribe the code to make protein.
What two things make up a chromosome?
Chromosomes are comprised of nucleotides and nitrogen base pairs. The nucleotides make up the columns of the DNA structure, and are repeating sequences of a 5-carbon sugar and a phosphate. The "rungs" of the DNA structure, similar to the rungs (steps) of a ladder, and made up of four variations of nitrogen base pairs.
What makes up the middle of a DNA molecule?
The nitrogen bases make up the center of the two strands of a DNA molecule.
A DNA strand is made of which make up which make up sentences?
A DNA molecule is composed of two strands of nucleotides.
What are the long chains that DNA make up?
DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.
What are the two components that make up of the backbone of the DNA?
Sugar and phosphate are the parts that make up the DNA backbone.
Known as one DNA molecule stretched out?
two strands make up a DNA molecule
