In DNA? Deoxyribose and phosphate.
In RNA, ribose and phosphate.
Ribose is a 5 carbon sugar, while phosphate is Phosphorus and Oxygen.
So, a chain is formed that goes from the 5' of the sugar (the 5' just means the 5th carbon of the 5 carbon sugar ring), to the 3' of the sugar, to an Oxygen, to a Phosphorus, to another Oxygen, to the 5' of the next sugar, to its 3' carbon, and so on and on and on for thousands or hundreds of thousands of repeating units.
The 'bases' are other chemical molecules hanging off the sugars, abbreviated as A, T, C and G, which just hang there by themselves in RNA, but in DNA tend to pair up with another chain that is of exactly the reverse and 'complement' of the first strand, (A pairs with T, C pairs with G) making the 'base pairs' of the famous DNA double helix.
Really just ends up looking like a twisted up ladder.

What are three compounds of a DNA nucleotide?
The three components of DNA are: base, sugar, and phosphate. A molecule of DNA consists of two strands. Each strand is a linear series of nucleotides. Each nucleotide consists of a base (a purine or pyrimidine), a pentose (five-carbon sugar), and a phosphate group. The sugar is between the base and the phosphate. In a strand, nucleotides are combined through their sugars and phosphates, in such a way that alternating sugars and phosphates form a sugar-phosphate backbone. The bases project at right angles to this backbone.
What contains a sugar a base and a phosphate group?
nucleotides that are the building blocks of nucleic acids are made up of sugar, a nitrogen base and phosphate group
Sugar phosphate and what make up the DNA molecule?
Nitrogenous bases (ATCG)
What monomer is made up of a base a sugar and a phosphate group?
Nucleotide:)
Does DNA contain phosphate?
"DNA is essentially made up of a sequence of nucleotides, each of which are associated with one molecule of phosphate." This is true, however not completely. Let's look at an example. Say we have a DNA molecule that is 10 base pairs long ( double stranded, so actually has 20 bases). The statement suggests we would have 20 phosphates in this molecule of DNA. However, we actually have 24. This is because the nucleotides situated at the 5' terminals of each strand have 3 phosphates rather than one. Since we have 2 5' terminals we have an excess of 4 phosphates which we did not account earlier, so instead of 20, we are now at 24 phosphates.
What makes up the backbone sides of DNA?
A ribose sugar linked by phosphate groups.
What makes up the outside of the dna ladder?
The sugar phosphate backbone.
What makes up the rail or sides of the DNA structure?
Backbone. A deoxyribose sugar and a phosphate group.
What 2 substances make up the backbone or the sides of the DNA molecule?
The sugar-phosphate backbone of DNA is made up of deoxyribose (a sugar) and phosphate.
What type of sugar makes up the backbone of the DNA molecule?
The sugar found in the backbone of DNA is the deoxyribose.
What is the backbone of DNA made of?
Phosphates and sugars.
Why does the DNA backbone not line up at each end?
The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the "sides" of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the "rungs" of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
What is the backbone of DNA and RNA?
The backbone of DNA is made up of deoxyribose, a sugar, and are linked together by phosphodiester bonds. RNA is similar but the sugar is called ribose.
What two parts make up the back bone of DNA?
Phosphate and Deoxyribose sugar are the two parts that form the backbone of DNA. They are joined by ester bonds.
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.
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.
Which chemicals make up the backbone of the double helix?
It is based on a repeated pattern of a sugar group and a phosphate group.
