NEET 2012 Biology question
Read the following four statements (A - D) (A) In transcription, adenosine pairs with uracil (B) Regulation of lac operon by repressor is referred to as positive regulation (C) The human genome has approximately 50,000 genes (D) Haemophilia is sex-linked recessive disease How many of the above statements are right ?
Answer: (2)
Solution
(A) Right - during transcription the DNA template base adenine pairs with uracil of the growing RNA (there is no thymine in RNA). (B) Wrong - regulation of the lac operon by the repressor is negative regulation (the repressor blocks transcription; the inducer
