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.
What else can I help you with?
How many strands are there in DNA?
DNA is made up of two strands.
What are the two parts of the DNA that make up the sides of the double helix?
I'm not sure I understand your question, but DNA is a huge molecule formed by two very long polynucleotide strands. They are linked together by hydrogen bonds between complimentary pairs of nitrogen bases. It looks something like a ladder. Sugar-phosphate would be like the rails of the ladder and the paired nitrogen bases would be like the steps. Hope this helps somewhat.
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 are Sugar in a DNA?
In DNA, sugars refer to the deoxyribose molecules that make up the backbone of the DNA double helix. These sugars are linked together by phosphate groups, forming the sugar-phosphate backbone of the 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 two components that make up of the backbone of the DNA?
Sugar and phosphate are the parts that make up the DNA backbone.
Which two molecular groups make up the backbone of dna?
deoxyribose and phosphate
The two exact copies of DNA that make up a chromosome are called?
Chromatids.
What two structures make up a single replicated chromosome?
DNA and Protein
How are the properties of water different from the two elements that make it up?

What two chemicals make up the rungs of the DNA ladder?
The two chemicals that make up the rungs of the DNA ladder are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs connect the two strands of the DNA double helix together.
Which are the two main parts that make up a chromosome?
A centromere and a pair of sister chromatids
Which two make up the backbone of DNA strands?
A deoxyribose sugar and phosphate groups.
What two structures make up the outside of the DNA ladder?
Easy.... Sugar and a phosphate.

Besides nitrogen bases what are the other two compounds that make up DNA?
Phosphate and deoxyribose.
