Question

What would be the chemical formula of a linear tetranucleotide that would have deoxyribose sugars and one of each of the possible nitrogenous bases in the DNA?

Answer 1

The chemical formula would be
CTGA or any of the combinations of the four nitrogenous bases
The nucleotide is made up of four bases which makes it a tetranucleotide and the arrangement of each bases create a linear geometry.

Answer 2

Answer:

The chemical formula of a linear tetranucleoide with deoxyribose and one of each DNA nitrogenous bases would be the one shown at the picture. The nucleotides do not need to be in the shown order, there can be other combinations.

Explanation:

A tetranuleotide is a compound of four (tetra means four) nucleotides joined together.

Linear means that the structure will be arranged in a straight line. So a linear tetranucleotide is a compound of four nucleotides arranged in a straight line.

A nucleotide is a compound of a phosphate, a sugar and a nitrogenous base. The sugar can be a ribose or a deoxyribose and the nitrogenous base can be adenine, guanine, cytosine, thymine (for DNA) or uracil (for RNA).

*  When the nucleotide is formed of phosphate, deoxyribose and adenine is called dAMP.  (green color in picture)

* When its structure is phosphate, deoxyribose and guanine is dGMP.  (orange color in picture)

* dCMP for the union of phosphate, deoxyribose and cytosine (blue color in picture) and finally for the compound of phosphate, deoxyribose and thymine is dTMP.  (purple color in picture)
