What is a key distinction between the Non-Homologous End Joining (NHEJ) and Homology-Directed Repair (HDR) pathways in the context of DNA repair following genome editing?

选项
A.NHEJ is more precise than HDR in repairing DNA breaks
B.HDR allows for the insertion of specific sequences, while NHEJ typically results in small insertions or deletions
C.NHEJ only occurs in plant cells, while HDR is universal across all organisms
D.NHEJ requires a template for repair, while HDR does not

Exploring the key ideas behind NHEJ and HDR helps separate the true distinctions from common myths. Option 1: 'NHEJ is more precise than HDR in repairing DNA breaks' — This is misleading. In general, NHEJ is quicker but error-prone and often introduces small insertions or deletions, whereas HDR uses a homologous ......Login to view full explanation
