A DNA nucleotide is one of two kinds of bases... a pyrimidine or a purine. The purine is a heterocyclic (two-ring) molecule with a 5 member and 6 member ring each containing 2 Nitrogens. Purines are just a single ring with 2 Nitrogens. Each base is paired with a sugar (ribose) less one oxygen (hence the prefix de-oxyribose). Some nucleotides also bear a methyl group. These methylated nucleotides help the body identify self from non-self DNA and also are used in determining which strand is the original strand after duplication for the purpose of DNA repair. There are 4 types of DNA nucleotides. Adenine, Guanine, Thymine, and Cytosine. There are others... but we don't use them often unless a mistake happens or a mutation or tautumeric shift occurs (whole other subject). There are a handful of others.
What else can I help you with?
How are nucleotides in a single strand of a DNA molecule linked together?
Nucleotides in a single strand of a DNA molecule are linked together by strong chemical bonds called phosphodiester bonds. These bonds connect the sugar and phosphate groups of adjacent nucleotides, forming a long chain that makes up the DNA molecule.
What macromolecules are made of nucleotides?
RNA and DNA.
What are the 4 DNA nucleotides?
The four DNA nucleotides are adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides pair up with each other to form the base pairs that make up the DNA double helix.
How many DNA bases are present in 8 DNA nucleotides?
There are 32 DNA bases in 8 DNA nucleotides.
What are repeating subunits of DNA and RNA called?
The repeating subunits of DNA and RNA are called nucleotides. Nucleotides are composed of a phosphate group, a sugar molecule (deoxyribose in DNA and ribose in RNA), and a nitrogenous base (Adenine, Thymine, Cytosine, and Guanine in DNA; Uracil replaces Thymine in RNA).
What are the monomers of DNA made of?
its made up of nucleotides
What does cell makes a mistakes and copy in its DNA?
nucleotides
How are nucleotides in a single strand of a DNA molecule linked together?
Nucleotides in a single strand of a DNA molecule are linked together by strong chemical bonds called phosphodiester bonds. These bonds connect the sugar and phosphate groups of adjacent nucleotides, forming a long chain that makes up the DNA molecule.
What compounds are the building blocks of DNA macro-molecules?
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.
What macromolecules are made of nucleotides?
RNA and DNA.
Is nucleotide related to DNA?
individual nucleotides make up the long strands of DNA.
What are two larger molecules made up of nucleotides?
DNA and RNA are made up of nucleotides.
What makes DNA a polymer?
DNA is a polymer because it is made of up of monomers of nucleotides that differ from each other by their bases. (Adenine, Guanine, Cytosine, and Thymine.)
What are precursors?
dna precursors are the thing that make up dna, nucleotides
The DNA of microorganisms is made up of subunits called?
The DNA of microorganisms is made up of subunits called nucleotides. These nucleotides consist of a sugar, a phosphate group, and a nitrogenous base. The sequence of these nucleotides forms the genetic information of the microorganism.
What acid makes up DNA?
DNA is made up of deoxyribonucleic acid (DNA), which is a long polymer composed of nucleotides. These nucleotides consist of a phosphate group, a sugar called deoxyribose, and one of four nitrogenous bases: adenine, thymine, cytosine, or guanine.
How is a gene related to the sequence of nucleotides?
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.
