regulating transcription

Question 1

what can inhibit the translation of mRNA

Answer 1

RNA interference

Question 2

what is RNA interference

Answer 2

mRNA molecule which has already been transcribed gets destroyed before its translated to create a polypeptide chain

Question 3

what is the RNA interference done by

Answer 3

small interfering RNA

Question 4

describe the process of RNA interference

Answer 4

• an enzyme can cut the mRNA into siRNA
• one strand of the siRNA then combines with another enzyme
• the siRNA enzyme complex can bind via complementary base pairing to another mRNA molecule
  -once bound the enzyme with cut up the mRNA so it cannot be translated
