Which of these proteins is considered to possess endonuclease activity? (Select all that apply)

Question

Quizplus · Accepted Answer

RecA, RecBDC, and transposase are all proteins that possess endonuclease activity. Endonucleases are enzymes that cleave the phosphodiester bonds within a DNA molecule. RecA is a protein that is involved in homologous recombination, and it cleaves the DNA strand at the site of the crossover. RecBDC is a protein complex that is involved in the repair of double-strand breaks, and it cleaves the DNA strand at the site of the break. Transposase is a protein that is involved in the movement of transposons, and it cleaves the DNA strand at the site of the transposon insertion.
