Correct Answerसही उत्तर
D. Har Gobind KhoranaD. हर गोबिंद खुराना
Explanationव्याख्या
The correct answer is Har Gobind Khorana.
According to the source, in 1968 Nirenberg won the Nobel Prize in Physiology or Medicine for seminal work on the genetic code.
He shared the award with Har Gobind Khorana of the University of Wisconsin and Robert Holley of Cornell University.
The book states that Khorana mastered the synthesis of nucleic acids, while Holley discovered the chemical structure of transfer-RNA.
Therefore the source-supported revision chain is: Nobel Prize in Physiology or Medicine — 1968 — work on genetic code — Nirenberg — Har Gobind Khorana — Robert Holley; Khorana — University of Wisconsin — synthesis of nucleic acids; Holley — Cornell University — chemical structure of transfer-RNA.
Among the four options, Har Gobind Khorana is therefore the intended answer.
The source does not give Nirenberg's full name in this entry, so it has not been expanded from outside knowledge.
Quick revision: Genetic Code → 1968 Nobel → Har Gobind Khorana among the given options.
Therefore option (d) is correct.
सही उत्तर Har Gobind Khorana है। स्रोत के अनुसार 1968 में Nirenberg को genetic code पर उनके seminal work के लिए Nobel Prize in Physiology or Medicine मिला। उन्होंने यह award Har Gobind Khorana, University of Wisconsin, और Robert Holley, Cornell University, के साथ share किया। Book बताती है कि Khorana ने synthesis of nucleic acids में mastery प्राप्त की, जबकि Holley ने transfer-RNA की chemical structure discover की। इसलिए source-supported revision chain है: 1968 — Nobel Prize in Physiology or Medicine — Genetic Code — Nirenberg — Har Gobind Khorana — Robert Holley; Khorana — University of Wisconsin — Synthesis of Nucleic Acids; Holley — Cornell University — Chemical Structure of transfer-RNA। दिए गए options में Har Gobind Khorana intended answer हैं। Source Nirenberg का full name इस entry में नहीं देती, इसलिए outside knowledge से expand नहीं किया गया है। Quick revision: Genetic Code → 1968 Nobel → Har Gobind Khorana। इसलिए विकल्प (d) सही उत्तर है।
