The Diagram Shown Here Is Part of an RNA Transcript

question 97

Multiple Choice

The diagram shown here is part of an RNA transcript containing four open reading frames (M, H, K, and L) and three introns (1, 2, 3) . The sites labeled d1-d3 are nucleotides immediately before each intron on the 5' side and those labeled a1-a3 are nucleotides immediately after each intron on the 3' side. Splicing out an intron involves a spliceosome facilitating the cleavage of the DNA at the d and a sites at either end of the intron. How many processed transcripts are possible in which two d sites and two a sites are cleaved?

• A)one
• B)two
• C)three
• D)four
• E)five
