Final answer:
C) Promoting chromatin remodeling. Long non-coding RNAs can regulate transcription by promoting chromatin remodeling.
Step-by-step explanation:
Long non-coding RNAs (IncRNAs) regulate transcription through various mechanisms. One method by which they do this is by promoting chromatin remodeling. Chromatin remodeling refers to the alteration of the structure of chromatin, which is the complex of DNA and proteins in the cell nucleus. By promoting chromatin remodeling, long non-coding RNAs can regulate the accessibility of DNA to transcription factors and RNA polymerase, thus influencing the transcription of genes.
