1.	A ssRNA shows inverted tandem repeat. What would be its secondary structure?(a) Linear(b) Hair pin(c) Stem-loop structure(d) CrucifixThe question was asked in an interview for internship.My doubt stems from Transcription in Prokaryotes : Termination in division Gene Expression : Transcription Prokaryotes of Cytogenetics
Answer» Correct option is (c) Stem-loop structure To EXPLAIN I WOULD say: A tandem repeat has some bases between the palindrome regions resulting in the formation of the loop. The remaining COMPLEMENTARY sequences of the palindrome FORMS the stem. In case of dsRNA similar SEQUENCE would form a crucifix while absence of intersecting sequence will form hairpin.
