Answer:
The question is incomplete.
However, I notice that your question is mainly dealing with
"Nucleotides with a single ring structure"
I tackled that part, also providing explanation to the point you focused on.
Explanation:
Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.
Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.
Answer:
The correct answer would be - triploid plant.
Explanation:
Triploidy is a condition which can be defined as the 3 set of chromosome in an organism, the extra set of chromosome may be come from the maternal organism or the paternal derived. Maternal derived triploidy known as the digynic while in in the case of the paternal derived called diandric.
In this case the sperm goes under the meiosis so the each gamete will have one chromosome of each set (I I I) while the egg failed to undergo meiosis so the gamete carry complete set of chromosome ( II II II ) after fertilization the outcome will be Digynic triploidy (III III III).
Thus, the correct answer would be - triploid plant.
