Which of the following pairs is incorrectly matched?a)Purines-Adenine ...
Purines-Adenine and Guanine
Purines are nitrogenous bases that consist of a double-ring structure. Adenine and guanine are both purines and are correctly matched as they are two of the five nitrogenous bases found in DNA and RNA.
Pyrimidines-Cytosine and Uracil
Pyrimidines are nitrogenous bases that consist of a single-ring structure. Cytosine and uracil are both pyrimidines and are correctly matched. Cytosine is one of the four bases found in DNA and RNA, while uracil is found only in RNA.
Nucleosides-Adenosine and Thymidine
Nucleosides are compounds consisting of a nitrogenous base bonded to a sugar molecule. Adenosine and thymidine are both nucleosides and are correctly matched. Adenosine consists of the purine base adenine bonded to the sugar ribose, while thymidine consists of the pyrimidine base thymine bonded to the sugar deoxyribose. Both adenosine and thymidine are found in DNA.
DNA-Basic biomolecule
This pair is incorrectly matched. DNA (deoxyribonucleic acid) is not a basic biomolecule, but rather a complex biomolecule that plays a central role in heredity and the storage of genetic information. DNA is a nucleic acid and is composed of nucleotides, which consist of a nitrogenous base (adenine, guanine, cytosine, or thymine), a sugar molecule (deoxyribose), and a phosphate group. DNA is responsible for transmitting genetic information from one generation to the next.
Therefore, the incorrect pair is option D, DNA-Basic biomolecule.
