Gibberellin is an important plant hormone that regulates several aspects of plant growth and development. Some statements are given below in relation to  signalling pathways:

a) The binding of gibberellin (GA) to its receptor leads to the degradation of the DELLA repressor by the 26S proteasome

b) Gibberellin binds to the GID1 receptor and induces a conformational change in the N-terminal domain of the receptor, allowing the receptor to interact with the TVHYNP and DELLA domains of the DELLA repressor

c) The formation of the GID1-repressor complex promotes the interaction between the repressor and the E3 ubiquitin ligase SCFTIR1 complex, leading to the ubiquitination and degradation

d) The gibberellin receptor GIBBERELLIN INSENSITIVE DWARF 1 (GID1) also itself function as an F-box protein

Which one of the following is the incorrect statements about GA  signalling pathway;

Precision will be reduced, but yield will be increased
Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.
