Q
What process can inhibit the translation if mRNA?
How?
A
Inhibited by RNA interference (RNAi)
-mRNA molecule that has already been transcribed gets destroyed before translation (to make polypeptide chain)
done by a small interfering RNA (siRNA)
2
Q
Explain RNA interference
A
-an enzyme can cut mRNA into siRNA
-one strand of siRNA combines with another enzyme
-siRNA-enzyme complex binds via complimentary base pairing to another mRNA molecule
-once bound, enzyme will cut up mRNA so cant be translated
