D. Protein	IV. alpha$\alpha$-amino acid

Choose the correct answer from the options given below :

### Core Logic Adenine (A) base pairs with Thymine (T) with 2 hydrogen bonds, and Cytosine (C) base pairs with Guanine (G) with 3 hydrogen bonds. For the given DNA strand: A rightarrow T$A \rightarrow T$ T rightarrow A$T \rightarrow A$ G rightarrow C$G \rightarrow C$ C rightarrow G$C \rightarrow G$ T rightarrow A$T \rightarrow A$ T rightarrow A$T \rightarrow A$ C rightarrow G$C \rightarrow G$ A rightarrow T$A \rightarrow T$ ### Step 1: Sequence Matching Given sequence: A T G C T T C A Complementary: T A C G A A G T

### Pattern Recognition DNA base pairing strictly follows Chargaff's rule: A=T and G≡C. Just swap A with T, and C with G in the exact order. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Chemistry: Biomolecules

### Core Logic Proteins are natural biopolymers. The fundamental building blocks (monomers) of all naturally occurring proteins are alpha$\alpha$-amino acids. In these molecules, both the amino group (-NH_2$-NH_2$) and the carboxyl group (-COOH$-COOH$) are attached to the exact same carbon atom, designated as the alpha$\alpha$-carbon. Because they are polymers of alpha$\alpha$-amino acids linked by peptide bonds, the hydrolysis of proteins (acidic, basic, or enzymatic) will cleave these peptide bonds to yield the constituent alpha$\alpha$-amino acids. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Chemistry: Biomolecules

### Core Logic A. RNA is regarded as the reserve of genetic information. (False - DNA is the reserve of genetic information). B. DNA molecule self-duplicates during cell division. (True - through replication). C. DNA synthesizes proteins in the cell. (False - RNA molecules synthesize proteins via translation, DNA only provides the code). D. The message for the synthesis of particular proteins is present in DNA. (True - the genetic code lies in the base sequence of DNA). E. Identical DNA strands are transferred to daughter cells. (True - through accurate replication and cell division, genetic continuity is maintained). ### Step 1: Final Conclusion The true statements are B, D, and E. Total number of correct statements is 3. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Chemistry: Biomolecules
