<span>Transposons are mobile elements that are very important in the evolution of the eukaryotic genome. </span> <span>For example, transposons are involved in the formation of introns. Evolution often deactivates DNA transposons via RNA interference, leaving them as <span>introns. They are also important in the production of antibody diversity via </span>V(D)J recombination <span>because the mechanism of this recombination is similar to that of some transposons (probably originated from it).</span> Another advantage of these mobile elements is in the formation of interspersed repeats within genomes which are created by transposition. Because interspersed repeats block gene conversion, they protect novel gene sequences from being overwritten by similar gene sequences.</span> <span>Transposons can contain many types of genes.</span>

How does the movement of materials across the cell membrane relate to an<br> organism’s survival?
ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening
