According to the widely accepted acid growth hypothesis, allows some main predictions except;

#Unit 6. System Physiology – Plant
  1. Auxin should increase the rate of proton extrusion and the kinetics of proton extrusion should closely match those of auxin-induced growth
  2. Neutral buffers should allows auxin-induced growth
  3. Compounds (other than auxin) that promote proton extrusion should stimulate growth
  4. Cell walls should contain a “wall loosening factor” with an acidic pH optimum

With respect to microRNAs, which, if any, of the following statements, is false?

a) A microRNA normally works by binding to perfectly complementary sequences within an RNA transcript, usually an mRNA.

b) Like the great majority of mRNAs an miRNA is usually produced as a larger precursor RNA that is capped and has a 3’ poly(A) tail.

c) The precursor miRNA undergoes different types of post-transcriptional cleavage by endoribonucleases that are specific for double-stranded target sequences.

d) A nuclear endoribonuclease called dicer cleaves the miRNA precursor so that it forms a stem-loop RNA.
