Transduction

Transduction, a process of genetic recombination in bacteria in which genes from a host cell (a bacterium) are incorporated into the genome of a bacterial virus (bacteriophage) and then carried to another host cell when the bacteriophage initiates another cycle of infection. In general transduction, any of the genes of the host cell may be involved in the process; in special transduction, however, only a few specific genes are transduced. It has been exploited as a remarkable molecular biological technique for altering the genetic construction of bacteria, for locating bacterial genes, and for many other genetic experiments.

what is a spore?

Ans 1: 
spore
noun

The definition of a spore is a small organism or a single cell being that is able to grow into a new organism with the right conditions.
An example of a spore is a flower seed.

Ans 2:

spore

1. BIOL. any of various small reproductive bodies, usually consisting of a single cell, produced by bacteria, algae, mosses, ferns, certain protozoans, etc., either asexually (asexual spore) or by the union of gametes (sexual spore): they are capable of giving rise to a new adult individual, either immediately or after an interval of dormancy
2. any small organism or cell that can develop into a new individual; seed, germ, etc.

Origin of spore

Modern Latin spora ; from Gr, a sowing, seed, akin to speirein, to sow ; from Indo-European base an unverified form (s)p(h)er-, to strew, sow from source spread, sprout

spored, spor′ing

to bear or develop spores

Ans 3:

spore

noun

1. A small, usually single-celled reproductive body that is resistant to adverse environmental conditions and is capable of growing into a new organism, produced especially by certain fungi, algae, protozoans, and nonseedbearing plants such as mosses and ferns.
2. A megaspore or microspore.
3. A dormant nonreproductive body formed by certain bacteria often in response to a lack of nutrients, and characteristically being highly resistant to heat, desiccation, and destruction by chemicals or enzymes.
