Cell Cycle

The phase in the cell cycle where the cell prepares for division by producing necessary proteins and organelles is the

The two main stages of the cell cycle are

DNA replication occurs in the

The spindle apparatus of plants differs from that of animals in not having:

During cell division, spindle fibres attach to a chromosome at:

What causes the number of chromosomes to reduce to half when a cell divides by meiosis?

Some students of SSC observed a thin cross-section from the root tip of an onion plant under the microscope. They found dividing cells at different stages of their life cycle. One of the students found a cell at late prophase and counted 28 chromosomes in it. The number of chromosomes in daughter cells should be:

The phase where chromosomes are separated into two daughter cells during mitosis is

During mitosis, chromosomes align at the cell’s equator in

Substance and energy required for the replication of DNA is accumulated in the cell during:

The diagram shows replication of chromosomes. What is the total number of chromosomes in this diagram?

The longest phase of meiosis is:

In meiosis, crossing over occurs during

The structure that holds sister chromatids together is the

A bivalent consists of:

The primary function of the cell cycle is

Crossing over does not occur in

Crossing over results in genetic recombination. It occurs between:

8. The cell shown in this diagram is passing through:

Chromosomal number of a fruit fly is 8. The gametes of the fruit fly contain:

All of the following events take place both in mitosis and meiosis except:

The phase in which the cell performs most of its normal functions is the
