- During meiosis, the sister chromatids separate during:
(1) Anaphase II
(2) Anaphase I
(3) The S phase
(4) Synapsis - 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 - Select the wrong statement:
(1) Cell growth is a continuous process
(2) Cytoplasmic content increase occurs only during one
specific stage in the cell cycle
(3) DNA synthesis occurs only during one specific phase
of cell cycle
(4) None of these - A picture of dividing Drosophila cell through a
microscope shows that the cell contains 8 chromosomes,
each consisting of two chromatids. The picture must
have been taken during:
(1) Mitotic metaphase
(2) Mitotic Anaphase
(3) Meiotic Anaphase II
(4) Meiotic Telophase II - Which of the following is false?
(1) The mitotic spindle is composed of microtubules
(2) In plant cells, cytokinesis is accomplished by the
formation of a cell plate
(3) The distribution of mitochondria between the
daughter cells during cytokinesis is random
(4) Chromatin condenses to form discrete, visible
chromosomes early in G1
