The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks who was responsible for the artificial synthesis of RNA and DNA in vitro. This requires knowledge of key scientists in molecular biology. 2. **Identifying Key Scientists**: The two prominent scientists associated with the synthesis of RNA and DNA in vitro are Okazaki and Kornberg. 3. **Kornberg's Contribution**: Arthur Kornberg is known for his work on DNA synthesis. He was awarded the Nobel Prize for his discovery of DNA polymerase, the enzyme responsible for DNA replication. 4. **Okazaki's Contribution**: Reiji Okazaki is recognized for his work on the synthesis of RNA and DNA, particularly in understanding the mechanisms of DNA replication and the discovery of Okazaki fragments. 5. **Analyzing the Options**: The options given are: - A) Okoya and Nirenberg - B) Okoya and Kornberg - C) Kornberg and Nirenberg - D) Nirenberg and Khurana Based on the contributions of Kornberg and Okazaki, we can eliminate options that do not include these scientists. 6. **Selecting the Correct Answer**: The correct answer is option B) Okoya and Kornberg, as they were both involved in the artificial synthesis of RNA and DNA in vitro. **Final Answer**: RNA and DNA were artificially synthesized "in vitro" by Okoya and Kornberg. ---

Nucleolus synthesises RNA

Depending upon the chemical nature of the template (DNA or RNA) and the nature of nucleic acids synthesised from it (DNA or RNA), list the types of nucleic acid polymerases.

Assertion :- In the same generation for transmission of genetic information RNA is better than DNA. Reason The protein synthesising machinery has evolved around RNA.

Primers are 1) chemically synthesised oligonucleotides that are complementary to the regions of DNA 2) chemically synthesised oligonucleotides that are not complementary to the regions of DNA 3) chemically synthesised, autonomously replicating circular DNA molecules 4) specific sequences present on recombinant DNA

RNA and DNA are chiral molecules. Their chirality is due to :

Assertion : The RNAi can be introduced in an organism by insertion of gene encoding complementary RNA only Reason : There are no methods by which in vitro synthesised complementary RNA can be inserted in an organism to induce RNAi (RNA interference)
