How is dna modified to inhibit transcription
Web4 sep. 2001 · The binding of transcription factors (TFs) to their target sites on gene promoters is essential for proper regulation of transcription. Selectively inhibiting the formation of TF/DNA complexes may therefore potentially decrease expression of a target gene of interest. Recently, approaches using minor groove-binding agents to inhibit …

WebIn areas of a DNA rich in CG repeats (i.e. CpG islands), cytosines may be methylated or an addition of a methyl group, allowing proteins involved in gene repression to recognize it. Or the change itself may inhibit the binding of transcription factor (s) to DNA. Web27 sep. 2024 · Transcription is the process of converting DNA code into RNA. Transcription occurs in the nucleus of a cell. ... Proteins can also be modified post-translationally to increase their activity or stability. ... Antibiotics can also target the translation machinery in bacteria to inhibit their growth and replication.
