Summary Introduction

To explain:

The reason for the existence of bacterial cells that can grow on a media without requiring threonine, leucine, or biotin and yet requiring methionine.

Introduction:

Lederberg and Tatum experimentally proved that a transformation occurs in the bacterial genome. They did so by placing bacterial cells that require different nutrients to survive on minimal media (media lacking essential nutrients). Some of the colonies from these mixtures, when placed on minimal media, were able to grow without any addition of nutrients. By this experiment, they concluded that genetic recombination had taken place that created new gene combinations capable of synthesizing all nutrients.

There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction.
