A) Crosslinking of bases on opposing DNA strands is especially problematic for cells because it presents an obstacle to DNA replication (the replication fork stalls) .
B) Crosslinking of bases on opposing DNA strands can be problematic for cells because it may present an obstacle to transcription (the RNA polymerase stalls) .
C) Double strand DNA breaks are a challenge for cells because if repair is not affected immediately the ends can drift apart quickly making correct repair impossible.
D) Repair of double stranded DNA breaks is easier in cells prior to DNA replication than after DNA replication has occurred.
