Adenine (A) and guanine (G) are purines.
Cytosine (C), Thymine (T), and Uracil (U) are pyrimidines.
Purines can only form hydrogen bonds with pyrimidines, and vice versa.
Therefore, the only base-pair bonds that can be formed are:
A-T
A-U
C-G

∙ 12y agoThey are different because each base has a different shape, and they have different names.
Each DNA nucleotide contains one of four different nitrogen bases. They are adenine, thymine, guanine, and cytosine.

∙ 12y agoThe four different nitrogenous bases; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are the parts that are different on different nucleotides.
These bases differ in their chemical structure:
The pyrimidines, Cytosine and Thymine have one ring (with different side chains).
The purines, Adenine and Guanine have two rings (with different side chains).

∙ 15y agothe chemical composition is very different. adenine will only connect to thymine, and guanine only connects to cytosine. almost an unlimited amount of combinations can be made!

The four types of nucleotides that make up DNA are named for their?
hydrogen bonds
What is the main difference between the four nucleotides that make up DNA is that they have different?
Bases
What are the 4 nucleotides for DNA?
A DNA nucleotide includes a phosphate, a deoxyribose sugar and a nitrogenous base. Only the nitrogenous base changes in the four different nucleotides. The four different bases are adenine (A), thymine (T), cytosine (C) and guanine (G).

Does DNA consists of five different nucleotides and does RNA consists of four different nucleotides?
No, first of in total, both RNA and DNA combined have five nucleotides, DNA and RNA, both consists of three of the same nucleotides, and have one that varies between the two. Both DNA and RNA, have the nucleotides, guanine, cytosine and adenine, however DNA, has the additional nucleotide thymine and RNA instead of thymine has uracil. So, DNA's nucleotides are guanine, cytosine, adenine and thymine, while RNA's are guanine, cytosine, adenine and uracil. To specifically answer the question, no DNA consists of four different nucleotides and RNA consists of three of the same nucleotides, with one differing.
Four subunits are needed to make a DNA molecule.?
Nucleotides Four nucleotides are needed to make a DNA molecule.
The four types of nucleotides that make up DNA are named for their?
hydrogen bonds
Four what subunits are needed to make a DNA molecule?
The subunits that make up the DNA molecule are DNA nucleotides. Each DNA nucleotide contains a deoxyribose sugar molecule, a phosphate group, and one of four nitrogen bases; adenine, guanine, cytosine, or thymine.
What is the main difference between the four nucleotides that make up DNA is that they have different?
Bases
The sequence of what encodes DNA information?
The sequence of four nucleotide 'bases' found in an organism's DNA "provides" an Organism's genetic make-up.
How do nucleotides cause living things to differ from on another?
the reason is that each living thing has a different order of nucleotides in its DNA
What are found in the DNA?
DNA nucleotides. Note that adenine, thymine, cytosine and guanine are NOT nucleotides, but they are only the bases which make the nucleotides different.
What are the 4 nucleotides for DNA?
A DNA nucleotide includes a phosphate, a deoxyribose sugar and a nitrogenous base. Only the nitrogenous base changes in the four different nucleotides. The four different bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
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.
How many different nucleotides can be present in the DNA molecule?
Four.
Is the base different from all four DNA nucleotides?
Yes
What are DNA precursors?
dna precursors are the thing that make up dna, nucleotides
