VERNALIZATION & FLOWERING+PYQS

FRIGIDA (FRI) gene promotes flowering repression by:

That points to B: Activating FLC. Compared with the other options, Activating FLC is the one that correctly describes the VERNALIZATION & FLOWERING concept. The wrong ones are A) Repressing FLC; C) Activating FT; D) Repressing SOC1. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

PHOTOPERIODISM+PYQS

FT gene product functions as:

Pick B: Florigen. Thinking through PHOTOPERIODISM step by step rules out the lookalikes and leaves Florigen. Skip these: A) Photoreceptor; C) Repressor of flowering; D) Growth inhibitor. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

ABCE & ABCDE MODEL +Synapdrgon flowering

K-domain of MADS-box proteins is mainly involved in:

The right choice is B: Protein–protein interaction. In ABCE & ABCDE MODEL +Synapdrgon flowering, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) DNA binding; C) RNA binding; D) Chromatin remodeling. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

ABC MODEL+PYQS

Which gene among the following is NOT a MADS-box gene?

That points to D: AP2. Compared with the other options, AP2 is the one that correctly describes the ABC MODEL concept. The wrong ones are A) AP3; B) PI; C) AG. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
