Answer:
Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome. Genome mapping provided a critical starting point for the Human Genome Project. Sequenced DNA fragments can be aligned to the genome map to aid with the assembly of the genome.
By inducing mutations, scientists have been able to increase genetic variation, which breeders depend on to produce crops with desirable traits, such as resistance to diseases and insects. ... Mutations can be induced in a variety of ways, such as by exposure to ultraviolet or ionizing radiation or chemical mutagens.

Answer:
Bacteria
Explanation:
Bacteria are a group of single celled organisms that are neither plants or animals.
Bacteria lack cell organelles such as the nucleus and the chlorophyll. 
They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.
Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.
