    Mitosis is broken into four phases, Prophase, Metaphase, Anaphase, and Telophase.
    Prophase - Is when genetic material inside of the nucleus condenses and the duplicated chromosomes become visual. The spindle fibers start to form outside of the nucleus.
    ...
    Telophase - The distinct and condensed chromosomes begin to spread out into a tangle of chromatin.
    After these four phases of mitosis happen a process called Cytokinesis takes place. Cytokinesis completes the process of cell division and splits one cell into two seperate cells.

    If transfromation is Successful, the recombinant DNA is integratedinto one of the chromosomes of thwe cell.
    Genetic Engineering:
    Genetic engineering alters the genetic makeup of an organism using techniques that introduce heritable material prepared outside the organism either directly into the host or into a cell that is then fused or hybridized with the host.This involves using recombinant nucleic acid (DNA or RNA) techniques to form new combinations of heritable genetic material followed by the incorporation of that material either indirectly through a vector system or directly through micro-injection, macro-injection and micro-encapsulation techniques.
    Genetic Engineering has spurred the growth of biotechnology, a new industry that is changing the way we interact with the living world.

    Isn't Evolution Just a Theory
    Bases Of Evolution
    Biological evolution, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.

    Charles Darwin Theory.
    The modern theory of evolution was developed by Charles Darwin, an amateur English naturalist, in the 19th century.When Darwin returned from graduation in 1831 he had a letter waiting for him from Captain Robert Fitzroy. He invited Darwin to join him on the Beagle. This voyage changed his thinking about natural history like the Earth's landforms and all living organisms. He proposed that all of the millions of species of organisms present today, including humans, evolved slowly over billions of years, from a common ancestor by way of natural selection. This idea said that the individuals best adapted to their habitat passed on their traits to their offspring. Over time these advantageous qualities accumulated and transformed the individual into a species entirely different from its ancestors (e.g. birds from reptiles, whales from bears, humans from apes, etc). During Darwin's travels he saw much more diversity in the plants and animals. He was so intrigues by the fact that so many plants and animals seemed so suited no matter what environment they are in. As Darwin continued on this voyage he collected many fossils. The more he studied fossils a question was aroused. He wanted to know why so many of these species disappeared and how were they related to living species? During Darwin's voyage The Galapagos Island influenced him the most. He learned from the vice-governor of the islands that the giant tortoises varied in predictable ways from one island to another, he saw many of these tortoise on the Galapagos. He always saw many types of small, ordinary looking brown birds hopping around looking for seeds. He collected many specimens. As he examined the birds more closely he noticed that some of the birds had differently shaped beaks. As well as collecting many specimens of living species, Darwin collected many fossils. Fossils are preserved remains of ancient organisms. Some of the fossils that he had found did not look anything like living organisms but some did. Darwin noticed that some fossils of extinct animals were similar to living species. On Darwin's way back home he thought of all the patterns he'd seen on the 5 year voyage, like the Galapagos mockingbirds that turned out to belong to three separate species and the brown birds that he had thought were wrens, warblers and blackbirds were actually all species of finches. With all these discovers Darwin started to wonder if all the different Galapagos species had evolved from South America ancestors. After years of researching and filling notebook after notebook with ideas about the species and evolution, evidence shows that species are not fixed and they could change by natural variations. Natural Variations are differences among individual species.Darwin's studies had a lot to do with observation and inference's. With all his discovers with the birds and tortoises he'd take what he observed and then make inferences on why they had those specific traits.

    Mitosis is broken into four phases, Prophase, Metaphase, Anaphase, and Telophase.
    Prophase - Is when genetic material inside of the nucleus condenses and the duplicated chromosomes become visual. The spindle fibers start to form outside of the nucleus.
    Metaphase - Across the center of the cell the centromeres line up and the centromeres of each chromosome are connected by the Spindle fibers to the two poles of the spindle.
    Anaphase - The chromosomes seperate and are moved along the spindle fibers to opposite ends of the cell.
    Telophase - The distinct and condensed chromosomes begin to spread out into a tangle of chromatin.
    After these four phases of mitosis happen a process called Cytokinesis takes place. Cytokinesis completes the process of cell division and splits one cell into two seperate cells.
