One similarity between DNA transposons and retrotransposons is that transposition results in movement of the original transposon to a different place in the genome. both can encode an enzyme required for mobilization. they both have poly-A segments at one end. during transposition, both go through an RNA form that is copied back into DNA.

Which is a characteristic of retrotransposons, but not of DNA transposons? may not have a function in their host have short DNA sequences that are inverted repeats of each other on the ends include a gene that encodes reverse transcriptase may be present in the genome from one to millions of times found in humans and other organisms

Compare DNA transposons and retrotransposons by completing the table below. If you have trouble clicking on some of the entries in the table, click on the first entry in a row and then press "tab" to move to cells to the right and then use up and down arrows to access answer options. DNA transposons retrotransposons enzyme required? [ Select ] [ Select ] important action of the enzyme? [ Select ] [ Select ] total number of copies of that TE in the genome immediately after a jump?

When two protein-coding genes have very similar nucleotide sequences and are located right next to each other on a chromosome, we can hypothesize that: a. one of them is a duplicate of the other, copied by a retrotransposon. b. they are nonhomologous. c. one of them is a pseudogene. d. they were produced by unequal crossing-over. e. they are transcribed in the same cell types.
