A quantity which has only magnitude but no direction is known as a scalar quantity.
Work is done only when a force produces motion.And it is the product of the force exerted on the the body and the distance moved by the body in the direction of force.
i.e. W =F.s
Work is actually the scalar product of force and displacement and hence is a scalar quantity.
W =F.s
i.e. W = Fs cos θ
where F is the force, s the displacement and θ the angle between force and displacement. According to the angle θ, work can be positive, negative, or zero.
Work is the outcome of the force and displacement caused by the body.
Force and displacement are vector quantities (they have both magnitude and direction) and the dot product of two vector quantites always gives a scalar quantity. So work has only magnitude but not direction.

G0 (quiescent phase) also known as the inactive stage of the cell cycle, is the stage when the cell remains metabolically active, but do not proliferate unless called on to do so. Such cells are used for replacing the cells lost during injury.

Kinetochore is a structure on chromatids at which the spindle fibres attach during cell division to pull the sister chromatids apart. Their proteins help to hold the sister chromatids together and also play a role in chromosome editing.
Kinetochore is observed in eukaryotes as an assembly on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.

Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another. Crossing over occurs between prophase I and metaphase I and is the process where two homologous non-sister chromatids pair up with each other and exchange different segments of genetic material to form two recombinant chromosome sister chromatids.

Mitosis is the process of cell division wherein the chromosomes replicate and gets equally distributed into two daughter cells. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).

Karyokinesis is defined as the division of the nucleus during the M phase of the cell cycle. ... The daughter chromosome is separated into two daughter nuclei. Cytokinesis, on the other hand, is defined as the division of the cytoplasm during the M phase of the cell cycle. Karyokinesis is followed by the cytokinesis in the mitotic division. In plant cells, the cytoplasm of the parent cell is divided by the formation of a cell plate in the middle of the parent cell. In animal cells, a cleavage furrow is formed by the plasma membrane, separating the two daughter cells.
