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. |
Answer
Changes in nucleosome spacing important in changing gene
expression
The correct two statements are below
When DNA is methylated and histones are deacetylated,
nucleosomes are relatively close together and transcription is
suppressed.
When DNA is unmethylated and histones are acetylated,
nucleosomes are spaced in the open configuration and transcription
can occur.
