What are the differences between miRNA and siRNA?
(Select all that apply.)
OmiRNAs carry the genetic information from the DNA in
the nucleus directly to the cytoplasm, and siRNAs are
involved in the degradation of specific mRNA molecules.
miRNAs are from 22 to 30 bases long, and siRNAs are 22
bases long.
O miRNAs carry the genetic information from the DNA in
the nucleus directly to the cytoplasm, and siRNAs help
with the processing of the initial mRNA transcribed from
DNA into a mature form.
miRNAs prevent translation of certain mRNAs, and
siRNAs are involved in the degradation of specific mRNA
molecules.
miRNAs are 20 to 22 bases long, and siRNAs are from 20
to 30 bases long.
What are some similarities and differences between siRNAs and miRNAs?
Explain how the miR-200 family of miRNAs behave as tumorsuppressorgenes. What happens when their expression is blocked or decreased?
