Retroviruses and their family members, the LTR-retrotransposons, possess an integrase protein (IN) that is required for the insertion of reverse transcripts into the genome of host cells. were candidates of elements that possessed defects in the integration step of transposition. Five mutations in Tf1 that resulted in low levels of integration were found to be… Continue reading Retroviruses and their family members, the LTR-retrotransposons, possess an integrase protein
