Why are changes in nucleosome spacing important in changing gene
expression?
Select the two correct answers.
Select the two correct answers.
| When DNA is unmethylated and histones are acetylated, nucleosomes are spaced in the open configuration and transcription can occur. |
| When DNA is methylated and histones are deacetylated, nucleosomes are relatively close together and transcription is suppressed. |
| Nucleosome spacing depends on maternal and paternal imprinting and influences organismal adaptability to environmental stress. |
| When DNA is phosphorylated or methylated and histones are acetylated, transcriptional activity is stimulated at specific DNA regions. |
