BENAR ATAU SALAH:
Mekanisme perbaikan kerusakan DNA homologous-directed repair (HDR) lebih akurat ketimbang nonhomologous end-joining (NHEJ).
Benar
Salah
Answer explanation
Homologous-directed repair (HDR) menggunakan suatu template khusus sehingga akan lebih akurat. Nonhomologous end-joining (NHEJ) hanya akan memotong ujung-ujung untai DNA yang rusak sehingga mengakibatkan hilangnya atau penambahan basa nitrogen (insertion or deletion, indel).
