what limits the frequency of replicative transposition of a transposon?
Homework Answers
The transposons and the mutual interest of the host cells may limit the transposition to very low frequency. Transposable elements are the segments of DNA that can activate from their original site and insert them into new sites in the genome. These elements are present in approximately all eukaryotic genomes. Half of the genome of humans consists of Transposable elements and the genomes of the larger plants are composed of more than 80% of transposable elements. Existing among these are the retrotransposons that proliferate through RNA intermediate. The DNA transposons move as DNA by an incise-and-stick mechanism. The majority of the insertions of transposons into genes affect gene damage. Due to this the host cells and the transposons limit the frequency of transposition.

Which of the following is a key difference between replicative and non-replicative transposition? a. In non-replicative transposition, the gene is deleted from the genome, and in replicative transposition the original copy of the gene is inverted. b. In non-replicative transposition, the transposition event occurs during mRNA processing, and in replicative transposition the transposition event is stimulated by RNA polymerase. c. In non-replicative transposition, the gene is deleted from its original location, and in replicative transposition one copy of the gene...

Which of the following statements correctly describes a DNA transposon? Flanking direct repeats are generated when a transposable element inserts into DNA. Transposable elements are mobile DNA sequences. A new copy of a transposable element is introduced at a new site, and the old copy always remains at the original site during replicative transposition. Transposable elements are thought to have played an important role in the evolution of many organisms. All of the above statements correctly describe a DNA transposon....

2. Mutation frequency A culture of E. coli is going to be mutagenized with transposons for a genetics experiment. The transposon used is a simple transposon containing a gentamicin resistance gene between the inverted repeat sequences, and it has had its transposase gene deleted so that after insertion, the transposon cannot insert into a second site in the genome or remove itself from the place where it first inserted. The culture is grown to a density of 1.5 x 106...

"Encode and decode a message using a substitution and transposition cipher." I'm not exactly sure what a substitution and transposition cipher are exactly, but I "think" it has to do with something like this: I want to encode then decode the string: "HELLO". I have: c(H) = (8 + 4)mod26 == 12mod26 == 12 H = 12 == L c(E) = (5+4)mod26 E = 9 == I c(L) = (12+4)mod26 L = 16 == P x2 c(O) = (15+4)mod26 O...
