How Many Nucleotides Make up a Codon? What is a codon and where is it found? DNA uses four nucleotides — adenine, cytosine, guanine and thymine — to code for the production of the 20 amino acids that make up all of the proteins found in living organisms.

The Structure of DNA The basic building block of DNA is called a NUCLEOTIDE. A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.

- Nucleotides are the monomer units that make up a DNA molecule. DNA nucleotides are composed of a deoxyribose sugar, a nitrogenous base, and a phosphate group.he building block of DNA is called the nucleotide, which is composed of a nitrogenous base (adenine, guanine, cytosine, or thymine), a five-carbon sugar (deoxyribose in DNA), … and one to three phosphate groups. + 16 others found this useful.

Glossary of HIV/AIDS-related Terms: Each DNA molecule is a long two-stranded chain. The strands are made up of subunits called nucleotides, each containing a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases, adenine, guanine, thymine, and cytosine, denoted A, G, T, and C, respectively. A given strand contains nucleotides bearing each of these four.

Nucleotides All nucleotides are composed of three parts: a five-carbon sugar, a phosphate, and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose, which is found in ribonucleotides and RNA, or deoxyribose, which is found in deoxyribonucleotides and DNA. The only difference between these two sugars is that deoxyribose has one fewer oxygen atom than ribose. The five carbon atoms in the sugar are numbered sequentially.

List Ways in which Prokaryotic and Eukaryotic DNA Differ These cells can also have smaller DNA structures called plasmids that contain additional information. The number of nucleotide base pairs in the prokaryotic chromosome ranges from 160,000 to 12.2 million, depending on the species. Eukaryotes frequently have multiple types of chromosomes with many more base pairs.

- The nucleotides in DNA are made up of three basic components, a sugar, a phosphate and one of four possible bases. The order and sequence of these bases is what encodes geneti … c information.ach nucleotide consists of:   * a 5 - carbon (pentose) sugar (ribose in RNA, deoxyribose … in DNA)  * a nitrogen-containing base (adenine, thymine, guanine, cytosine and uracil)  * a phosphate group   In DNA or RNA the phosphate groups link sugar molecules together to make up a polynucleotide.

Nucleotides in DNA Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring. The order of nucleotides along DNA polymers encode the genetic information carried by DNA.

Understanding DNA DNA is made up of four bases: adenine (A), cytosine (C), thymine (T), and guanine (G). The order of these bases is called the DNA sequence. Whenever a particular base is present on one side, its complementary base is found on the other side. In the example above, see how the bases always occur in complementary pairs.

- What is the basic structure of all the nucleotides that make up DNA? Each nucleotide consists of a phosphate, a sugar (deoxyribose), and a nitrogenous base, such as, adenine, guanine, cytosine, thymine.denine and thymine form two hydrogen bonds, while cytosine and guanine form three. DNA strands have a 5' end and a 3' end. The 5' end is characterized by a phosphate group coming off of the fifth carbon in the sugar.

- Quick Answer. Nucleotides are made up of a phosphate group, a five-ring sugar and a nitrogenous base. Nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic (RNA), contain repeating nucleotides. Nucleotides link together to form nucleic acids by connecting the phosphate group of one nucleotide to the sugar of another. Continue Reading.
