Solution

OBJ 1.2d:

Evolution and DNA fidelity, the unity and diversity of life:

The structure of nucleus best reveals the evolutionary unity of prokaryotes (plants, animals, fungi). All the prokaryotes contain the DNA in a membrane-bound organelle called nucleus. The structure of mitochondria also reveals evolutionary unity, which carries its own DNA. The Inheritance of the mitochondrial DNA is a non-nuclear inheritance. They are inherited from the mother only. Though the entire living beings share some percent of DNA in common, diversity is there, this defines the process of evolution. During each cycle of replication, mistakes occur and proof reading facility corrects most of these mistakes. However, certain process such as natural selection and gene tic drift favours the occurrence of mutations that increase the survival and reproductive properties of the organism, these are the main processes involved in evolution.

Bacterial genetics provide a lot of information regarding the history of evolution, and also they show different evolutionary histories. This is because natural selection always wants to evolve a species that better uses the resources and (balanced) with successful reproduction. Several species are evolved during this struggle. To evolve a single useful mutation, it takes hundreds of years, and a single useful ancient mutation is carried for at least 1, 00 000 years. Unwanted genes and mutations are not carried for much long years.
