Regulating taanslation
| Term | Definition |
|---|---|
| What can inhibit translaiton of the mRNA produced from target genes | RNA interference |
| When is this | When an mRNA molecule that has already been transcribed gets destroyed before it is translated to create a polypeptide chain |
| This is done by | Small interfering RNA (siRNA) |
| An enzyme can cut the mRNA into siRNA One strancd of the siRNA then combines with another enzyme This siRNA enzyme complex will bind via complementary base paring to another mRNA molecule | |
| Once bound the enzyme with cut the mRNA so it cannot be translated |
