Question

The gene promoter sequences, commonly used in gene cloning experiments are derived from __________________.

• A. TMV(Tobacco Mosaic Virus)
• B. TSWV(Tomato Spotted Wilt Virus)
• C. CMV(Cucumber Mosaic Virus)
• D. CaMV(Cauliflower Mosaic Virus)

Answer 1

The correct option is A TMV(Tobacco Mosaic Virus)

The gene promoter sequences, commonly used in gene cloning experiments are derived from MV(Tobacco Mosaic Virus). Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobaco virus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins.

So, the correct option is 'A'.
