Document Summary
Much smaller than autonomous counterpart. (cid:120) both are in the genome (cid:120) transposase polypeptide recognizes tir of the transposable element. Lecture 10 the infested genome: ltr retrotransposons, lines and sines. Transposons (cid:120) cut and paste: dna transposons, transposition (cid:120) rna intermediate, retrotransposons, retrotransposition. 3: virus particle: membrane envelope and nucleocapsid: protein capsid with 2 strands of rna and 2 copies of reverse transcriptase. This produces single- stranded rna (cid:198) retroviral genome. It is an rna transcript that can encode for proteins: buds off producing a viral particle. Primary function uses rna as a template to produce dna. All dna pol requires a primer which is contributed by the host. Transcript called pbs = primer binding site. F(cid:396)ee (cid:1007)" e(cid:374)d: double-stranded dna and rna- Dna hybrid strand (r and u5: enzyme ribonuclease h degrades rna in the hybrid, strand disassociates from template then re-associates further down.
