Which of the Following are Characteristic of Intrinsic Terminator Elements

Question

Which of the following are characteristic of intrinsic terminator elements?
A)They contain an inverted repeat.
B)They contain a hairpin loop.
C)They contain several T's in the nontemplate strand of DNA.
D)Only They contain an inverted repeat and they contain a hairpin loop are correct.
E)They contain an inverted repeat,they contain a hairpin loop,and they contain several T's in the nontemplate strand of DNA are correct.

Accepted Answer

Intrinsic terminators in bacteria typically have a region forming a hairpin loop due to an inverted repeat, followed by a string of adenines in the template strand, which corresponds to several thymine (T) bases in the nontemplate strand of DNA. This structure facilitates the termination of transcription.
