Cell Cycle and Division

The ________, which had undergone duplication during the S phase of interphase, now begins to move towards opposite poles of the cell.

Four ________ are formed at the end of meiosis II.

There is no ________ during interkinesis.

In some organisms, karyokinesis is not followed by cytokinesis as a result of which ________ arises leading to the formation of syncytium (e.g., liquid endosperm in coconut)

________ is followed by prophase II, much simpler prophase than prophase I.

________ represents the transition to metaphase.

________ or the equational division is usually restricted to the diploid cells only.

________ is the mechanism by which conservation of a specific chromosome number of each species is achieved across generations in sexually reproducing organisms, even though the process, per se, paradoxically, results in a reduction of chromosome number by half.

Though for ________ has been divided into four stages of nuclear division (karyokinesis), it is very essential to understand that cell division is a progressive process and very clear- cut lines can not be drawn between various stages.

During the ________, proteins are synthesized in preparation for mitosis while cell growth continues.

The ________ is divided into two basic phases.

________ is marked by the initiation of condensation of chromosomal material.

Variations are very important for the ________.

Crossing over is the exchange of genetic material between two ________.

The production of offspring by ________ includes the fusion of two gametes, each with a complete haploid set of chromosomes.

During the ________, the cell is metabolically active and continuously grows but does not replicate its DNA.

Since the ________ in the parent and progeny cells is the same, it is also called equational division.

________ are formed from specialized diploid cells.

The bivalent chromosomes align on the ________.

In ________, during the S phase, DNA replication begins in the nucleus, and the centriole duplicates in the cytoplasm.

The ________ represents the phase when the actual cell division or mitosis occurs.

The ________ untangled during the process of chromatin condensation.

The ________ is due to mitosis.

________ are seen to be composed of two chromatids attached together at the centromere.

It corresponds to the interval between mitosis and ________ replication.

________ or synthesis phase marks the period during which DNA synthesis or replication takes place.

The ________ starts with the nuclear division, corresponding to the separation of daughter chromosomes (karyokinesis), and usually ends with the division of cytoplasm (cytokinesis)
