PHYTOCHROME+PYQS

Photoreversibility of phytochrome refers to:

Answer: B) Interconversion between Pr and Pfr. For PHYTOCHROME, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Degradation of phytochrome in light; C) Binding of chromophore; D) Movement into nucleus. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

ABCE & ABCDE MODEL +Synapdrgon flowering

Tetramers in Quartet model are formed by association of:

The right choice is B: Two dimers. 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) Four monomers; C) Three dimers; D) Five monomers. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

ABCE & ABCDE MODEL +Synapdrgon flowering

In Quartet model, functional unit regulating organ identity is:

Answer: C) Tetramer. For ABCE & ABCDE MODEL +Synapdrgon flowering, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Monomer; B) Dimer; D) Pentamer. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

ABCE & ABCDE MODEL +Synapdrgon flowering

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

D fits best: AP2. Keep the ABCE & ABCDE MODEL +Synapdrgon flowering basics straight and AP2 stands out as the precise answer. Avoid: A) AG; B) PI; C) AP3. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

ABCE & ABCDE MODEL +Synapdrgon flowering

Class E genes act mainly as:

Pick C: Co-factors for ABC genes. Thinking through ABCE & ABCDE MODEL +Synapdrgon flowering step by step rules out the lookalikes and leaves Co-factors for ABC genes. Skip these: A) Structural proteins; B) Hormones; D) Enzymes. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
