Vedclass · Answer

(A) Statement $(i)$ is correct: During transcription,adenosine $(A)$ pairs with uracil $(U)$ in $RNA$.Statement $(ii)$ is incorrect: Regulation of the $lac$ operon by a repressor is referred to as negative regulation,as the repressor protein binds to the operator to inhibit transcription.Statement $(iii)$ is incorrect: The human genome contains approximately $20,000-25,000$ genes,not $50,000$.Statement $(iv)$ is correct: Haemophilia is a well-known sex-linked recessive disorder.Therefore,statements $(i)$ and $(iv)$ are correct. The total number of correct statements is $2$.
