A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases (adenine, guanine, thymine, cytosine). 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.
What else can I help you with?
Sugar phosphate and what make up the DNA molecule?
Nitrogenous bases, such as adenine, thymine, cytosine, and guanine, along with sugar phosphate groups, make up the DNA molecule. These nitrogenous bases are paired together to form the characteristic double helix structure of DNA.
Which four bases make up a molecule of DNA?
The bases in DNA are: Adenine(A), Thymine(T), Guanine(G), Cytosine(C) when they pair up: A-T, C-T
The water molecule is made up of the bases?
Water molecule contain hydrogen and oxygen.
If DNA molecule is compared to a spiral staircase what part make up the steps?
pairs of nitrogen bases
Three thing make the structure of a DNA molecule?
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
What makes up the middle of a DNA molecule?
The middle of a DNA molecule consists of nitrogenous bases (adenine, thymine, cytosine, and guanine) that pair up to form the genetic code. These bases are connected by hydrogen bonds, forming the double helix structure of DNA.
What are the names of the four bases that make up the rungs of the DNA molecule?
Adenine, Guanine, Cytosine, Thymine (replaced by Uracil in RNA)
What determines the mRNA sequence?
The genetic code is determined by the specific sequence of four nucleotide bases that make up DNA. The bases are guanine, adenine, thymine, and cytosine.
A long thread like molecule that includes genes?
DNA is a very long strand of a molecules, made up of four bases connected in pairs and spiraling into a double helix. Sequences of these bases are what make up genes.
Is the sides of the DNA molecule are made up of repeating nitrogen bases and sugars?
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
What does Nitrogen bases floating in the nucleus pair up with on each half of the DNA molecule?
When a nitrogen bases floating in the nucleus ipair up with the basis on each half of the DNA molecule. Remember that the pairing of bases follows definite rules: A always pairs with T, while G always pairs with C. Once the two new bases are attached, two new DNA are formed.

What makes up the sides o f a DNA molecule?
A DNA molecule consists of two strands that are made up of nucleotides. Each nucleotide is composed of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The two strands are connected by hydrogen bonds between complementary nitrogenous bases.
