Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is normally expressed in new seedlings, which prevents flowering. When a plant is exposed to cold temperatures, FLC expression decreases and the plant produces flowers. FLC is regulated through epigenetic modifications. Based on this information, you should expect which of the following in histone proteins near the FLC gene: 1.In new seedlings, histones will be acetylated; while in the cold, histone methylation occurs 2.In new seedlings, histones will be methylated; while in the cold, histone acetylation occurs 3.In new seedlings, histones will be methylated; while in the cold, histone deacetylation occurs

Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is normally expressed in new seedlings, which prevents flowering. When a plant is exposed to cold temperatures, FLC expression decreases and the plant produces flowers.
FLC is regulated through epigenetic modifications. Based on this information, you should expect which of the following in histone proteins near the FLC gene:
1.In new seedlings, histones will be acetylated; while in the cold, histone methylation occurs
2.In new seedlings, histones will be methylated; while in the cold, histone acetylation occurs
3.In new seedlings, histones will be methylated; while in the cold, histone deacetylation occurs
