○ side a because in the image the molecule is double stranded, has deoxyribose as the sugar and has thymine as a base.
○ side b because in the image molecule is single stranded, has ribose as the sugar and has the base uracil.

☐ is a molecule that uses dna instructions to build proteins. it is usually single stranded, has ribose in its structure and has the bases a, u, c and g.
☐ is a molecule that is the blueprint for building proteins. it is double stranded, has deoxyribose in its structure, and has the bases a, t, c and g

Explanation:

First Question (Evidence for the Answer)

To determine the correct side, we recall the structures of DNA and RNA. DNA is double - stranded, has deoxyribose sugar, and contains thymine. RNA is single - stranded, has ribose sugar, and contains uracil instead of thymine.

• For the first option (Side A): The description of a double - stranded molecule with deoxyribose and thymine matches DNA, not the evidence we would use for RNA - related identification (assuming the context is about RNA, but let's check the second option too).
• For the second option (Side B): The description of a single - stranded molecule with ribose and uracil matches the structure of RNA. So if we are identifying RNA, Side B's evidence (single - stranded, ribose, uracil) is correct.

We know the characteristics of RNA:

• RNA is involved in using DNA's instructions to build proteins. It is typically single - stranded, has ribose as its sugar, and its nitrogenous bases are adenine (A), uracil (U), cytosine (C), and guanine (G).
• The second option describes DNA: DNA is the blueprint (genetic material that holds the code for proteins), it is double - stranded, has deoxyribose, and has bases A, T, C, G.

Answer:

Side B because in the image molecule is single stranded, has ribose as the sugar and has the base uracil.
