A primitive eukaryote was discovered that displayed a unique nucleic acid as its genetic material. Analysis provided the following information: (a) The general X-ray diffraction pattern is similar to that of DNA but with somewhat different dimensions and more irregularity. (b) A major hyperchromic shift is evident upon heating and monitoring UV absorption at 260 nm. (c) Base-composition analysis reveals four bases in the following proportions. Note that xanthine and hypoxanthine are both purines. (d) About 75 percent of the sugars are deoxyribose, while 25 percent are ribose. Part A Based on these findings, which characteristics does this unique nucleic acid have

Answer:

c and d

Explanation:

(C) Even though this option seem incomplete, the information revealed also shows it's unique.

One characteristic this nucleic acid has that is different from other nucleic acid is the purines. The purines in both DNA and RNA are adenine and guanine while this nucleic acid has xanthine and hypoxanthine which are the found in the tissues and fluids of other organisms.

(d) Also, it's nucleotide has a mixture of two types of ribose sugars which is unusual because a DNA molecule has deoxyribose sugar while a RNA molecule has a ribose sugar - none of the two nucleic acids have a mixture of both types of sugar.
