Hello,
I hope this helps!
chromosomes that carry genetic information align in the equator of the cell before they split off into two daughter cells
Explanation:
During metaphase, the chromosomes that carry genetic information align in the equator of the cell before they split off into two daughter cells with identical genetic material. Metaphase is the third stage of mitosis, which is a phase of the cell cycle where chromosomes in the nucleus are divided between two cells.
<h2>Epigenetic modification </h2>
Explanation:
A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA
Answer:
Mesoscale winds are better known as local winds or regional winds. A local wind can persist anywhere from several minutes to several days. Local winds can be driven by temperature and pressure differences or by variations in topography, the shape and height of Earth's surface features.
