Answer (3) Zygotene
Sol. Synapsis is a process by which homologous chromosomes come to lie side by side in pairs.
The process of synapsis takes place during zygotene stage of prophase-I of meiosis-I.
Arrange the following events of meiosis in correct sequence (i) Crossing over (ii) Synapsis (iii) Terminalisation of chiasmata (iv) Disappearance of nucleolus (a) (i), (ii), (iii), (iv) (b) (ii), (iii), (iv), (i) (c) (ii), (i), (iv), (iii) (d) (ii), (i), (...
Dissolution of the synaptonemal complex occurs during : (1) Pachytene (2) Zygotene (3) Diplotene (4) Leptotene
During cell growth, DNA synthesis takes place on (a) S-phase (b) G1-phase (c) G2-phase (d) M-phase.
The stage during which separation of the paired homologous chromosomes begins is : (1) Diakinesis (2) Diplotene (3) Pachytene (4) Zygotene
Match the stages of meiosis in column I to their characteristic features in column II and select the correct option using the codes given below. Column I Column II A. Pachytene (i) Pairing of homologous chromosomes B. Metaphase I (ii) Terminalisation of ...
The separation of two chromatids of each chromosome at early anaphase is initiated by (a) the interaction of centromere with the chromosomal fibres (b) the elongation of metaphasic spindle (c) the force of repulsion between the divided kinetochores (d) all ...
Which of the following is not a characteristic feature during mitosis in somatic cells ? (a) Chromosome movement (b) Synapsis (c) Spindle fibres (d) Disappearance of nucleolus
Match the following events that occur in their respective phases of cell cycle and select the correct option : (a) G1 phase (i) Cell grows and organelle duplication (b) S phase (ii) DNA replication and chromosome duplication (c) G2 phase (iii) Cytoplasmic ...
Attachment of spindle fibers to kinetochores of chromosomes becomes evident in (1) Metaphase (2) Anaphase (3) Telophase (4) Prophase
In a mitotic cycle, the correct sequence of phases is (1) G1, G2, S, M (2) S, G1, G2, M (3) G1, S, G2, M (4) M, G1, G2, S,
