Drag each tile to the correct box. rna interference is a mechanism of gene regulation in eukaryotes. arrange the steps by which rnai carries out gene regulation in the correct order.

Answer

3,1,2,4

Explanation:

Through the mechanism of RNA interference (RNAi), short RNAs can inhibit gene  expression. RNAi can function at transcriptional level, translational level, and mRNA stability.

RNAi mechanism has numerous biological functions; it can affect development, for instance  in the worm C. elegans, or it can be utilized by plants to evade viral infection.

These short RNAs (abt 23 bp long) also known as siRNAs (short interfering RNAs) are  products of long dsRNAs which are cleaved by nuclease Dicer. The siRNAs regulate a  nuclease complex called RISC (RN-induced silencing complex) leading to repression of gene  expression via three distinct ways;

a) Destroy mRNAs that have complementary sequence with the siRNA

.

b) Inhibit translation of mRNAs that have complementary sequence with the siRNA.

c) Induce chromatin modification within the promoter of these homologous (complementary)  genes, thus silencing them.

just here for the other one bc they put up with u

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
