Motion of sister Chromatids toward opposite poles of the cell occurs by
1. | Shortening of microtubules attached to centromere |
2. | Shortening of microtubules attached to kinetochores |
3. | Shortening of microtubules attached to Metaphase plate |
4. | Shortening of microtubules attached to other homologous chromosomes |
Tetrad of cells is a result of
1. Meiosis I
2. Meiosis II
3. Mitosis
4. Prophase II
Simultaneous splitting of the centromeres of each chromosomes occur in
1. Anaphase I
2. Anaphase II
3. Metaphase
4. Prophase II
Which of the following phases is equivalent to Prophase II?
1. | Prophase |
2. | Prophase I |
3. | Metaphase |
4. | Mitosis |
By the end of Prophase II, chromosomes become
1. | Compact |
2. | Loose |
3. | Elongated |
4. | Decondensed |
When does Prophase II start usually?
1. | Chromosomes are fully elongated |
2. | Before chromosomes are fully condensed |
3. | Before chromosomes are fully elongated |
4. | After chromosomes are fully elongated |
Prophase II
1. | Simpler than Prophase but complex than Prophase I |
2. | Complex than Prophase I |
3. | Simpler than Prophase I |
4. | All of these |
Interkinesis
1. | Long lasting in some cells |
2. | Involves S phase |
3. | In between Meiosis I |
4. | No DNA replication |
The stage between two meiosis is
1. Cytokinesis
2. Interkinesis
3. Interphase I
4. Interphase
The separation of homologous chromosomes while attachment of sister chromatids remain associated at their centromere is a characteristic feature of which of the following
1. Diplotene
2. Pachytene
3. Anaphase I
4. Anaphase
