Question

Split gene is a gene ___________________.

• A. Whose entire sequence are not retained in RNA
• B. Whose entire sequences are retained in RNA
• C. Which has promoter but no operator
• D. Which has operator but no promoter

Answer 1

The correct option is A Whose entire sequence are not retained in RNA

A split gene consists of both exons and introns when the post-transcriptional modification happens, the introns which are non-coding genes are removed and only exons which are protein coding genes are retained in the mature RNA.

So, the right answer is option 'Whose entire sequence are not retained in RNA'.
