A nucleotide does not form a molecule: sugar, salt, phosphoric acid or nitrogen base? This question was answered by Mr. Andrzej Junak from Dąbrowa Górnicza.
In the Thursday episode, Mr. Andrzej Junak, an IT engineer, started his game. He managed to answer six questions correctly without using any of the lifebuoys.
Mr. Andrzej heard the seventh question, worth PLN 40,000, about the structure of a nucleotide.
The molecule does not form a nucleotide:
C: phosphoric acid
D: nitrogen base.
A nucleotide is the basic building block of nucleic acids: deoxyribonucleic acids, or DNA, and ribonucleic acids, or RNA.
The nucleotide is made up of a phosphoric acid and a sugar residue: deoxyribose (for DNA) or ribose (for RNA). The whole thing is completed with one nitrogen base: adenine, guanine, cytosine or thymine (in DNA) and uracil (in RNA).
So the correct answer to the above question is answer B.
