Coding Strand of DNA
When pointing to DNA transcription, the coding strand is found to be the DNA strand whose base sequence is indistinguishable from the base sequence of the RNA transcript developed. It is this strand that comprises the codons, while the non-coding strand comprises the anti-codons.
Nucleotide
Both DNA and RNA are composed of organic molecules known as nucleotides. Hence, nucleotides are known as the basic building blocks of nucleic acids. These substances play a role in various processes such as cell signalling, enzyme reactions, metabolism, and so on.
Structure of Cytosine
Cytosine is among the five primary nitrogenous bases of which DNA and RNA and are being used in storage and transportation of genetic makeup within a cell. Adenine, guanine, thymine as well as uracil are the remaining four nucleobases.
![This image depicts a series of chemical reactions and transformations used to produce specific compounds, A, B, and C.
### Chemical Reaction Sequence:
1. **Cyclopentyl Bromide Transformation:**
- **Reactants and Reagents:**
- Initial compound: Cyclopentyl bromide.
- Reagents: 1. Magnesium (Mg); 2. Carbon dioxide (CO₂).
- **Product C:** The sequence transforms cyclopentyl bromide into a new compound, labeled C, after the two-step reaction with magnesium and carbon dioxide.
2. **Aniline Derivative Transformation:**
- **Reactants and Reagents:**
- Initial compound: Aniline derivative.
- Reagents: 1. HONO (Nitrous acid) and H₂SO₄ (Sulfuric acid); 2. CuCN (Copper(I) cyanide).
- **Product A:** This reaction sequence involves converting the aniline derivative into a new compound, A, using diazotization followed by cyanation.
3. **Synthesis of Compound B:**
- **Reactants and Reagents:**
- Intermediate: Compound A.
- Reagent: Hydrogen gas (H₂) in excess is used to produce compound B from compound A.
- Compound B is further reacted with DCC (Dicyclohexylcarbodiimide) and an unspecified nitrogen compound (IN).
- **Final Product:** This step yields a compound with a phenyl group, an amine linkage, a carbonyl group, and a cyclopentyl moiety. Dicyclohexylurea (DCU) is a byproduct of the reaction.
### Additional Notes:
- **DCC Role:** Dicyclohexylcarbodiimide (DCC) is commonly used in peptide synthesis to facilitate amide bond formation.
- **Byproduct:** DCU is formed when DCC is used in the reaction, indicative of peptide bond formation or similar processes.
This sequence demonstrates the transformation of simple organic compounds through multi-step synthesis, an essential concept in organic chemistry for understanding the creation of complex molecules from simpler precursors.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F96c43769-2331-4d91-b7f9-4a256a33e785%2F10459eab-a1ab-4ecf-82ec-a932522a85ea%2Fuss8re_processed.jpeg&w=3840&q=75)
