Explanation:

Building Blocks: Nucleotides

• Both DNA and RNA are made of nucleotides (this is the fundamental unit for both nucleic acids).
• Each nucleotide has three parts:

1. Phosphate group (provides the acidic/phosphate component of the nucleotide).
2. Sugar (either ribose for RNA or deoxyribose for DNA, forms the backbone structure).
3. Nitrogenous base (contains the nitrogen - rich ring structure that participates in base - pairing).

• Nucleotides are the monomers (building blocks) that link together to form polymers (long chains, like DNA or RNA strands).

Sugar Differences

• RNA Sugar:
• Contains ribose sugar (the 5 - carbon sugar specific to RNA).
• Has two hydroxyl groups (-OH) (on the 2' and 3' carbons of the ribose sugar).
• Makes RNA more reactive (the extra hydroxyl group makes it less stable and more prone to chemical reactions).
• DNA Sugar:
• Contains deoxyribose sugar (lacks an -OH group on the 2' carbon compared to ribose).
• Has one hydroxyl group (only on the 3' carbon).
• "Deoxy" means "without oxygen" (refers to the absence of the oxygen in the hydroxyl group on the 2' carbon of the sugar).
• Makes DNA more stable (the lack of the 2' - OH group makes it less reactive and more stable for long - term storage of genetic information).

The Base Pairs

• DNA Bases:
• \(A=\) Thymine (T) (Adenine pairs with Thymine in DNA through two hydrogen bonds).
• \(T=\) Adenine (A) (Thymine pairs with Adenine).
• \(G=\) Cytosine (C) (Guanine pairs with Cytosine through three hydrogen bonds).
• \(C=\) Guanine (G) (Cytosine pairs with Guanine).
• RNA Bases:
• \(A=\) Uracil (U) (Adenine pairs with Uracil in RNA).
• \(U=\) Adenine (A) (Uracil, which replaces Thymine, pairs with Adenine).
• \(G=\) Cytosine (C) (Guanine pairs with Cytosine in RNA as well).
• \(C=\) Guanine (G) (Cytosine pairs with Guanine in RNA).

(Note: For the first fill - in "Can temporarily form ______ structures during certain processes", if we assume it's about RNA (since RNA can form secondary structures like hairpins temporarily), the answer would be "secondary" (like stem - loop or hairpin secondary structures that RNA can form during processes like transcription or translation regulation).)
