Question
Which one of the following is wrongly matched?
Transcription- Writing information from DNA to t-RNA
Translation- Using the information in m-RNA to make protein
Repressor protein- Binds to an operator to stop enzyme synthesis
Operon- Structural genes, operator, and promoter
According to the NCERT text and the Central Dogma of molecular biology, transcription is the process of copying genetic information from one strand of DNA into mRNA (messenger RNA), which carries the code for protein synthesis. While tRNA is also produced via transcription, it functions as an adapter molecule (Source: ) rather than the carrier of genetic information for the protein sequence. Therefore, describing transcription as writing information to t-RNA is chemically imprecise in this context compared to the other options. Translation uses mRNA information to synthesize proteins (Source: ), Repressor proteins bind to the operator to prevent transcription (Source: ), and an Operon comprises structural genes, an operator, and a promoter (Source: ).
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Molecular Basis of Inheritance. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.

Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable. Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repairing mechanism. In light of the above statements, choose the most appropriate answer from the options given below:
