The human genome contains about 5000 “processed pseudogenes,” which are derived from the insertion of DNA copies of mRNA molecules derived from many different genes. Predict the structure of these pseudo-genes. Would each type of processed pseudogene be expected to found a new family of retrotransposons within the human genome? Would the copy number of each type of processed pseudogene be expected to increase significantly over evolutionary time, as the copy number of the Alufamily has? Explain your answers.
