Certain mutations in non-Hox genes actually produce homeotic mutants due to a failure to modulate chromatin acetylation appropriately. What is this influence on cellular "memory" called?
which of these four?
| epigenetic |
| RNA interference |
| genetic |
| chromatin remodeling |
The correct option is 'Epigenetic'
The epigenetic memory is defined as the set of modifications to the cell's DNA that do not alter the DNA sequences. They have been inherited from the cell from which it descends. RNA interference (RNAi) is defined as a process in which RNA molecules inhibit gene expression or translation. Chromatin remodeling is the rearrangement of chromatin from a condensed state to a transcriptionally accessible state. Transcriptional activation or repression can be achieved by Epigenetic modifications to histone proteins, by altering the structure of chromatin.
