Most probably used host organism is E.coli.
The genetic makeup AAA BB is called its genotype. It is defined as the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
Cell division is how a single-celled organism reproduces.
A single organism in an environment is called an individual
Single-cell organisms are linked to genetic transformation, they acquires new genetic material from the environment
Meiosis
This is known as mutagenesis. This can be achieved in a number of ways, in either a controlled or random manner. Random mutagenesis can be achieved through exposure to UV light or free radicals such as hydrogen peroxide, which would create different mutations in each cell. Controlled mutagenesis can be performed to ensure that all organisms (single- or multi-celled) have the same genetic makeup. One method to modify DNA in a controlled manner involves the use of modified viruses.
A single celled organism is called unicellular.
a bacteria
Mitosis
Clone a human from a single cell of an adult human.
asexual reproduction
