Document Summary
If it changes protein translation or does nothing it still considered a mutation: dna damage if a change is not a double stranded change, they are physical abnormalities, damage can be repaired, ex. Inverted repeat sequence the same dna sequence running in opposite directions. It enables the transposase enzyme to identify the ends of the. Rna copy of the transposable element: transposes by a copy-and-paste mechanism that is unlike any other te, first, the retrotransposon (which is a dna element integrated into the chromosomal dna), is transcribed into a complementary. Rna copy: next an enzyme called (cid:498)reverse transcriptase(cid:499) (cid:523)an enzyme that uses rna as a template to make a dna copy of the retrotransposon. Dnas are free to roam around in the genome. Elements (tes) are calssified as: transposons, retrotransposons. Elements (tes) are classified as: insertion sequence. Reversible shifts of proton position in a molecule. Wild type: role of uv, ionizing radiation and ros in mutagenesis.
