Energy is lost when machines don’t work right.

We can’t add more energy to the universe.

We can’t destroy energy that exists in the universe.

Energy changes from one form to another.

kap26 [50]

Answer:

Georgia is the world's leading producer of Kaolin (china clay).

Explanation:

Kaolin or china clay contains the mineral kaolinite mainly. It also contains varying amounts of other minerals like muscovite, feldspar, quartz, etc. In order to prepare it for commercial use, the clay in its natural form is then chemically treated and washed with water to remove the other minerals.

Kaolin is extensively used in the ceramic industry and the paper-coating industry. The high fusion temperature and white burning characteristics are used in the ceramic industry for the manufacture of chinaware, porcelain, and refractories. In the paper-coating industry, the kaolin is mixed with the cellulose fiber in the paper sheet. This gives the paper its color, opacity, and printability. It is also used as a pigment additive in paints, as a filler in plastic and rubber compounds, and in pharmaceuticals.

The dicer enzyme processes dsRNA and forms siRNAs, which suppress the expression of target genes by cutting mRNA. 1) siRNA 2) RNA.

<h3>What are siRNA fragments?</h3>

siRNA means small interfering RNA. This is a silencing RNA molecule involved in the RNA interference mechanism, intervening in the expression of a specific gene.

siRNAs are complementary double-stranded RNA molecules composed of about 20-21 nucleotides. siRNA originates from a long double-stranded RNA (dsRNA).

The dicer enzyme cuts dsRNA molecules and produces siRNA. siRNAs suppress the expression of target genes when cutting messenger RNA.

siRNAs suppress the expression of target genes by cutting the complementary messenger RNA (mRNA) into two halves. This is accomplished by the interaction of the siRNA with the RISC complex (RNA-induced silencing complex).

The two mRNA halves are later degraded by the cellular machinery, leading to the suppression of the gene expression.

siRNAs also participate in other pathways related to RNAi, such as in antiviral defense or in the chromatin structure organization.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme dicer cuts dsRNA into smaller fragments called (1) siRNA, which form a complex with RISC and degrade specific (2) RNA.
