ABCE & ABCDE MODEL +Synapdrgon flowering

Latest questions in this category.

30 questions

Peloria mutant of Linaria is caused due to inactivation of:

That points to C: CYCLOIDEA. Compared with the other options, CYCLOIDEA is the one that correctly describes the ABCE & ABCDE MODEL +Synapdrgon flowering concept. The wrong ones are A) DIV; B) RAD; D) AG. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Mutation in CYCLOIDEA gene leads to:

Correct option is B, Radial symmetry. In ABCE & ABCDE MODEL +Synapdrgon flowering problems like this, the accurate statement is Radial symmetry; the others are common mix-ups. Not these: A) Bilateral symmetry; C) Extra petals; D) Loss of sepals. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

RAD represses which gene to control ventral identity?

Pick C: DIV. Thinking through ABCE & ABCDE MODEL +Synapdrgon flowering step by step rules out the lookalikes and leaves DIV. Skip these: A) CYC; B) DICH; D) SEP. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

RADIALIS (RAD) gene encodes a transcription factor of family:

Answer: B) MYB. 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) bHLH; C) MADS-box; D) AP2. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Loss of LFY gene results in:

That points to B: Conversion of flowers to inflorescences. Compared with the other options, Conversion of flowers to inflorescences is the one that correctly describes the ABCE & ABCDE MODEL +Synapdrgon flowering concept. The wrong ones are A) Extra petals; C) Only carpels; D) Early flowering. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Which gene is Arabidopsis homolog of Antirrhinum FLO?

Correct option is B, LFY. In ABCE & ABCDE MODEL +Synapdrgon flowering problems like this, the accurate statement is LFY; the others are common mix-ups. Not these: A) AP1; C) AG; D) PI. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

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.

Floral quartet complexes bind DNA through which domain?

Go with B — MADS domain. Under ABCE & ABCDE MODEL +Synapdrgon flowering, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Homeodomain; C) bZIP domain; D) HLH domain. When two options sound similar, choose the one that matches the textbook definition most tightly.

Loss of Class C gene function leads to formation of:

That points to C: Repeated sepals and petals. Compared with the other options, Repeated sepals and petals is the one that correctly describes the ABCE & ABCDE MODEL +Synapdrgon flowering concept. The wrong ones are A) Only sepals; B) Only petals; D) Leaf-like organs. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Loss of Class A function results in absence of:

Answer: A) Sepals and petals. 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: B) Petals and stamens; C) Stamens and carpels; D) Carpels only. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Class A and Class C genes shows which interaction?

That points to C: Mutual antagonism. Compared with the other options, Mutual antagonism is the one that correctly describes the ABCE & ABCDE MODEL +Synapdrgon flowering concept. The wrong ones are A) Synergistic; B) Additive; D) Independent. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

AGAMOUS (AG) gene mainly specifies:

Answer: C) Stamens and carpels. 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) Sepals; B) Petals; D) Ovules. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
