Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is expressed in new seedlings, which
wlad13 [49]

Answer:

- New seedlings: histone acetylation

- After cold exposure: histone methylation

Explanation:

Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In <em>Arabidopsis</em>, vernalization is associated with histone modifications at <em>FLC</em> chromatin. The <em>FLOWERING LOCUS C </em>(<em>FLC</em>) is a MADS-box gene that acts as a repressor of flowering in <em>Arabidopsis</em>. Epigenetic modifications control the expression of the <em>FLC</em> gene. The <em>FLC</em> gene is expressed at low temperatures due to histone acetylation at <em>FLC</em> chromatin, and thereby the expression of <em>FLC</em> mRNA transcripts ensures that the <em>Arabidopsis</em> plant cannot flower. Subsequently, as the <em>Arabidopsis</em> plant is exposed to cold, <em>FLC</em> is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.

What is the difference between cell division in plant cells and cell division in animals cells?
Semmy [17]
There are not many differences between animal and plant cell division, only that when it comes time for the cell to divide during cytokinesis, the plant cell grows a cell plate in between the two nuclei, and the animal cell forms a cleavage furrow<span> and divides.
Hope this helped!
