To determine which elements would be found in an analysis of DNA but not in glucose, we need to understand the chemical composition of DNA and glucose.
DNA (deoxyribonucleic acid) is a complex molecule that contains four nitrogenous bases (adenine, guanine, cytosine, and thymine), a sugar molecule called deoxyribose, and a phosphate group.
Glucose, on the other hand, is a simple sugar (monosaccharide) composed of carbon, hydrogen, and oxygen. Its chemical formula is C6H12O6.
From this information, we can identify the elements that would be found in an analysis of DNA but not in glucose:
1. Phosphorus (P): Phosphorus is an essential component of DNA, as it is present in the phosphate group that connects the nucleotide units in DNA. Therefore, phosphorus would be found in an analysis of DNA but not in glucose.
2. Nitrogen (N): Nitrogen is crucial in DNA since it forms hydrogen bonds with the nitrogenous bases, enabling the double-stranded structure of DNA. In glucose, nitrogen is not present, so nitrogen would be found in an analysis of DNA but not in glucose.
Based on this analysis, the correct answers are Phosphorus and Nitrogen.
The elements that would be found in an analysis of samples of DNA of a cell but not in the glucose from the cell are:
1. Phosphorous
2. Nitrogen
