During meiosis I in human, one of the daughter cells receives:

(1) Only maternal chromosomes

(2) A mixture of maternal and paternal chromosomes

(3) The same number of chromosomes as a diploid cell

(4) A sister chromatid from each chromosome

Chromosomes decondense into diffuse chromatin:

(1) At the end of telophase                

(2) At the beginning of prophase

(3) At the end of interphase              

(4) At the end of metaphase

The total DNA content of each daughter cell is reduced during meiosis because:

(1) Chromosomes do not replicate during the interphase preceding meiosis I

(2) Chromosomes do not replicate between meiosis I and II

(3) Half of the chromosomes from each gamete are lost during fertilization

(4) Chromosome arms are lost during crossing over

Which of the following does not occur during mitotic prophase?

(1) Disappearance of the nuclear envelope

(2) Chromosome condensation

(3) Migration of centrosomes towards the cell poles

(4) Synapsis of homologous chromosomes

Which of the following is not true for sister chromatids?

(1) They arise by replication during S phase

(2) They segregate from each other during each mitotic anaphase

(3) The usually contain identical versions of the same genetic information

(4) They segregate from each other during meiosis I

Which of the following statements is True?
(1) Cell plate represents the middle lamella between the walls of two adjacents cells
(2) At the time of cytokinesis, organelles like mitochondria and plastids get distributed between the daughter cells
(3) Cytokinesis in plant cell is centrifugal and takes place by cell-plate formation while animal cells by furrowing / cleavage and is centripetal
(4) All are correct

Crossing is an enzyme-mediated process. The enzyme is:

(1) DNA ligase      

(2) Recombinase  

(3) RNAase           

(4) DNAase

Match Column-I with Column-II:
Column-I                                                                               Column-II
I. Chromosomes are moved to spindle equator                        A. Pachytene
II. Centromere splits and chromatids apart                               B. Zygotene
III. Pairing between homologous chromosomes takes place    C. Anaphase
IV. Crossing between homologous chromosomes                    D. Metaphase

(1) I-A, II-B, III-C, IV-D                               

(2) I-B, II-C, III-D, IV-A

(3) I-D, II-C, III-B, IV-A                               

(4) I-C, II-A, III-D, IV-B

Which event is not associated with prophase I?

(a) Synizesis                   (b) Synapsis                   (c) Segregation     (d) Terminalization

A cell cycle includes:

1. Interphase + M-phase / divisional phase

2. Prophase + Metaphase + Anaphase + Telophase

3. G₁ + S + G₂ – phase

4. Karyokinesis + Cytokinesis
