Question

What are the similarities between DNA and RNA molecules?

Both are linear nucleotide molecules with nitrogenous bases perpendicular to the sugar-phosphate backbone.
Both are double stranded molecules with nitrogenous bases and ribose sugar backbone.
Both are linear nucleotides with the same nitrogenous bases.
Both are linear single stranded molecules and contain sugar-phosphate backbone.

Answer 1

Both DNA and RNA are made up of monomers called nucleotides.

Both RNA and DNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine.

They are both necessary for the cell to produce proteins.

DNA and RNA both contain pentose sugars.

DNA makes mRNA which then is translated into protein.

Step-by-step explanation:

Answer 2

Both are single-stranded and contain a sugar-phosphate backbone.

DNA and RNA are both composed of nucleotides, which consist of a phosphate group, a sugar molecule (deoxyribose in DNA and ribose in RNA), and a nitrogenous base. While DNA is typically double-stranded and RNA is usually single-stranded, the common feature is the single-stranded nature with a sugar-phosphate backbone. The other options mentioned (double-stranded molecules with nitrogenous bases and having ribose sugar and the same nitrogenous bases) do not apply universally to both DNA and RNA.
