Fig. 4From: Diverse transposable element landscapes in pathogenic and nonpathogenic yeast models: the value of a comparative perspectiveMajors steps of reverse transcription for LTR retrotransposons. The gray box represents retrotransposon RNA with major sequence features not drawn to scale: LTR sequences U3, R, and U5; gag and pol ORFs; PBS- primer binding site; PPT- polypurine tract. The lavender shape indicates the tRNA primer, dashed blue arrows indicate newly synthesized DNA, and solid blue lines indicate DNA synthesized in a previous step.Back to article page
