<span>The answer is free-market. One view is that a free market is a framework in which the costs for products and enterprises are controlled by the open market and purchasers, in which the laws and strengths of free market activity are free from any intercession by an administration, value setting syndication, or other specialist.</span>

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.

Suppose we found a solar system with the property described below. In light of what you have learned about the formation of our

adelina 88 [10]

Answer:

Surprising

Explanation:

This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.

Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star

Hence, the given discovery is surprising

A recessive allele on the x chromosome is responsible for red-green color blindness in humans. Alleles are C = normal and c = co

Sergeeva-Olga [200]

Answer:

1/2

Explanation:

The allele for the red-green color blindness is X-linked recessive. The father of the woman was colorblind (X^cY) which means that the woman is a carrier for the allele and has genotype (X^cX). The genotype of the colorblind male would be X^cY. A cross between a carrier woman and a color-blind man would produce progeny in following ratio= 1/2 colorblind daughter: 1/2 normal daughter: 1/2 colorblind son: 1/2 normal son.

Therefore, there is a 50% probability that their first son is colorblind.
