Identify the event in meiosis mediated by the enzyme recombinase
1 Synaptic pairing
2 Terminalization
3 Crossing Over
4 Interkinesis
Explanation:
C Crossing over is a process which occurs in pachytene stage of prophase-I of meiosis-I during cell division. Recombinase enzyme mediated in crossing over, between non-sister chromatics of chromosome. This process is facilitated by an enzyme called recombinase.

After meiosis \(I\), the resultant daughter cells have
1 Four times the amount of DNA in comparison to haploid gamete.
2 Same amount of DNA as in the parent cell in S phase.
3 Twice the amount of DNA in comparison to haploid gamete.
4 Same amount of DNA in comparison to haploid gamete.
Explanation:
C Meiosis-I is a reductional division, which means that the resultant cell will have half the number of chromosomes as diploid parent cells. Meiosis is a specialized form of cell division that produces reproductive cells such as plants, fungal spores, sperm and egg cells. The overall process of meiosis produces four daughter cells is haploid because it has half the number of chromosomes as the original parent cell. - After meiosis-II, daughter cells will contain half the number of chromosomes and half of the amount of DNA is comparison to the parent cell.

The chromosomes align at the equator and the microtubules' from opposite poles of the spindle get attached to the kinetochores of sister chromatids are in
1 Metaphase-I
2 Telophase-I
3 Metaphase-II
4 Telophase-II
Explanation:
C Metaphase II- During Metaphase spindle fibers attach to the centromere of each pair of sister chromatids. The sister chromatids line up at the equator or center of the cell. This is also known as the metaphase plate. Metaphase is a stage during the process of cell division occur.

In meiosis two homologous chromosomes form bivalents by
1 synaptonemal complex
2 Golgi complex
3 Complex medium
4 Initiation complex
Explanation:
A Synaptonemal complex is that stage which indicates that chromosome synapsis, The synaptonemal complex form during the early stage of meiotic prophase-I. It is a ladder like complex that hold the two homologous chromosomes together. The pair of synapsed homologous chromosomes is called a bivalent or tetrad.
