Final answer:
LTR retrotransposons encode enzymes needed for transposition and contain flanking long terminal repeats (LTRs). Examples include retroviruses, Ty elements in yeast, and Gypsy elements in Drosophila. The promoter associated with LTR retrotransposons is located in the 5' UTR and recognizes RNA polymerase II.
Step-by-step explanation:
LTR retrotransposons encode various enzymes needed for transposition, including reverse transcriptase, endonuclease, and integrase. They also contain flanking long terminal repeats (LTRs) which are sequences that help with the integration of the retrotransposon into the genome. Examples of LTR retrotransposons include retroviruses, Ty elements in yeast, and Gypsy elements in Drosophila.
The promoter associated with LTR retrotransposons is located in the 5' untranslated region (UTR) and it recognizes RNA polymerase II. This promoter allows for the transcription of the retrotransposon genes, including those encoding the enzymes required for retrotransposition.
