After meiosis I, the resultant daughter cells have
1. | same amount of DNA as in the parent cell in S |
2. | twice the amount of DNA in comparison to haploid |
3. | same amount of DNA in comparison to haploid gamete |
4. | four times the amount of DNA in comparison to haploid gamete |
Crossing over takes place between which chromatids and in which stage of the cell cycle?
1. | Non-sister chromatids of non-homologous chromosomes at Zygotene stage of prophase I. |
2. | Non-sister chromatids of homologous chromosomes at Pachytene stage of prophase I. |
3. | Non-sister chromatids of homologous chromosomes at Zygotene stage of prophase I. |
4. | Non-sister chromatids of non-homologous chromosomes at Pachytene stage of prophase I. |
The correct sequence of phases in cell cycle is:
1.
2.
3.
4.
Cells in phase:
1. terminate the cell cycle
2. exit the cell cycle
3. enter the cell cycle
4. suspend the cell cycle
Some dividing cells exit the cell cycle and enter the vegetative inactive stage. This is called the quiescent stage . This process occurs at the end of:
1.
2. S phase
3.
4. M phase
Identify the correct statement with regard to phase (Gap 1) of interphase:
1. | The reorganisation of all cell components takes place. |
2. | The cell is metabolically active and grows but does not replicate its DNA |
3. | Nuclear division takes place |
4. | DNA synthesis or replication takes place. |
Dissolution of the synaptonemal complex occurs during :
1. | Zygote | 2. | Diplotene |
3. | Leptotene | 4. | Pachytene |
Match the following with respect to meiosis:
Column I | Column II | ||
(a) | Zygotene | (i) | Terminalization |
(b) | Pachytene | (ii) | Chiasmata |
(c) | Diplotene | (iii) | Crossing over |
(d) | Diakinesis | (iv) | Synapsis |
Select the correct option from the following:
Options: | (a) | (b) | (c) | (d) |
1. | iv | iii | ii | i |
2. | i | ii | iv | iii |
3. | ii | iv | iii | i |
4. | iii | iv | i | ii |
Attachment of spindle fibers to kinetochores of chromosomes becomes evident in:
1. | Anaphase | 2. | Telophase |
3. | Prophase | 4. | Metaphase |
During Meiosis 1, in which stage synapsis takes place?
1. | Pachytene | 2. | Zygotene |
3. | Diplotene | 4. | Leptotene |
