Final answer:
The global genomic pathway of Nucleotide Excision Repair (NER) is slower, less efficient, and responsible for correcting DNA strands in the non-transcribed parts of the genome.
Step-by-step explanation:
The method of repair that can be slower, less efficient, and responsible for correcting DNA strands in the parts of the genome that are not currently being transcribed is the global genomic pathway of NER (Nucleotide Excision Repair).
Nucleotide excision repair is a process that recognizes bulky, helix-distorting changes in DNA and repairs them. It can repair damage affecting longer strands of 2-30 bases. The global genomic pathway of NER is responsible for repairing DNA lesions throughout the genome, including areas that are not actively transcribed.
In contrast, the transcription-coupled pathway of NER is responsible for deploying repair enzymes to genes that are actively being transcribed, ensuring efficient and timely repair.
