Answer:
The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

Explanation:
- It <em>helps in understanding and preventing genetic diseases.</em>
Genome mapping projects like the human genome project made it possible to map regions of the genome associated with disease. These regions which often arise through mutations, may be cloned and identified through diagnostic methods. This <em>helps in understanding and preventing genetic diseases, along with providing possible treatment targets in drug and gene therapeutics.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.
Further Explanation:
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Answer:
Metamorphic - existing rocks are exposed to extreme conditions
Sedimentary - layers of sediment dry together
igneous - magma or lava solidifies
C. The birds had different diets. The bird's beaks evolve depending on their diet!

The answer is he was crazy and was glad that he had improved. In addition to separate peace the significance of finny’s shame at even thinking gene would take added roommate is that gene could swap him. Gene denotes to the correctness of being thrown into the naguamsett river on the first day of the winter session since it was his entrance into a new time in his life which is a step to self-confidence.
