In sea urchin DNA, which is double-stranded 17% of the bases were shown to be cytosine. The percentages of the other three bases expected to be present in this DNA are:
The 3'-5' phosphodiester linkages inside a polynucleotide chain serve to join:
1. | One nucleoside with another nucleoside |
2. | One nucleotide with another nucleotide |
3. | One nitrogenous base with pentose sugar |
4. | One DNA strand with the other DNA strand |
Which one of the following pairs of nitrogenous bases of nucleic acids is wrongly matched with the category mentioned against it?
1. Thymine, Uracil - Pyrimidines
2. Uracil, Cytosine - Pyrimidines
3. Guanine, Adenine - Purines
4. Adenine, Thymine - Purines
