Like dna, rna is a long string of nucleotides encased in a large molecule. however, there are three aspects of its structure that makes it different from dna. what are these aspects? (select all that apply.)you selected: rna is a single-stranded molecule.the sugar in each nucleotide of rna is ribose.rna’s thymine base is replaced by urcil

All of the listed aspects are correct

Explanation:

Deoxyribosenucleic acid and Ribosenucleic acid are the two nucleic acids. They are polymers made up of nucleotide monomers. Both DNA are composed of

sequence of nucleotides but they have three main structural differences. They are:

1. Unlike DNA that has a double-helical structure formed by the hydrogen bonds that link two complementary nucleotide bases, the RNA is a composed of nucleotide sequence in a single shorter strand.

2. In the RNA molecule, one of the components that makes up its building block (nucleotide) is a five-carbon sugar called Ribose. In the DNA molecule, one oxygen atom is deficient in the sugar, hence the sugar in the DNA is called Deoxyribose.

3. Another component of the nucleotide that makes up the RNA and DNA structure are the nitrogenous bases, which are four in number viz: Adenine, Guanine, Cytosine and either Thymine or Uracil depending on the nucleic acid. Thymine only occurs in DNA while Uracil only occurs in the RNA molecule.
