Question

Which of the following describes a likely model for the insertion of a simple transposon? A.) Any host sequence is cleaved to generate staggered ends of characteristic length, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon. B.) A characteristic host sequence is cleaved to generate staggered ends, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon. C.) A characteristic host sequence is cleaved to generate staggered ends, the transposon with direct repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon. D.) A characteristic host sequence is cleaved to generate blunt ends, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the blunt ends are ligated to the transposon.

The ends of eukaryotic chromosomes typically have 5' extensions called telomeres. True or False

Explanation / Answer

A characteristics host sequence is cleaved to generate staggered end the transposins with direct repeat sequence at each end inserts between the staggered end and staggered end are filled in and lagated to the transposing.

The tip of chromosomes have specialised cap that is called telomere. It varies 5' to 3' hence it is true
