all that apply.
Homework Answers
In Eukaryotic gene expression, ds rna plays an important role in expression .
Double stranded RNA regulate gene expression by a process called RNA interference . In this process , ds rna is broken into short fragments which :
- may lead to nuclear modification and increase heterochromatin;
- may destroy mRNA by binding to specific regions ,
- by modifying mRNA which inhibits translation.
By all these ways , ds rna can inhibit gene expressession.
So , Correct choices should be :

Identify the true statements about RNA interference. Select all of the true statements. Duplex RNA is cleaved by the Dicer enzyme complex. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short, single-stranded RNA segments that are about 45 nucleotides long. RNA interference can temporarily suppress the expression of a target gene. miRNAs suppress gene expression by interfering with transcription.

Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...

Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...
