Chapter 11, Problem 9TY
Summary Introduction
Introduction:
The CRISPR-Cas system is a defense mechanism present in some species of bacteria and archaea. This system provides defense against foreign invaders. It is an effective mechanism against bacteriophages.

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.

- Why Cas9 requires a single guide RNA (sgRNA) ?arrow_forwardCarrow_forwardmiRNA is distinct from siRNA solely because: Question 9 options: miRNA is always an imperfect complement while siRNA is always a perfect complement. miRNA encodes for a protein, whereas siRNA targets viruses. Argonaute chooses the miRNA strand to be used to target RNAs, while Dicer chooses the siRNA strand to used to target RNAs. Dicer chooses the miRNA strand to be used to target RNAs, while Argonaute chooses the siRNA strand to used to target RNAs. miRNA is from an endogenous source (e.g., encoded in chromosomal DNA) while siRNA is from an exogenous source (e.g., an RNA virus).arrow_forward
