History of DNA Technology During the early1960s‚ there was great progress being made in beginning to understand the structure of genes and the mechanisms of their replication‚ expression‚ and regulation in prokaryotes and the viruses that began to infect them (Berg 2010). However at the time it was still unknown as to whether or not these findings applied to eukaryotes. This is because the tools used at the time for exploring genetic properties were not fit for the task. By the spring of 1972‚ the

1. Outline the Steps of DNA: a. DNA Replication begins at the Origin of Replication b. Helicase cuts hydrogen bonds and separates DNA in half c. Semiconservative replication produces two copies that each contained one of the original strands and one entirely new strand. d. Topoisomerases catalyze and guide the unknotting of DNA e. Single Strand Binding Proteins attach to the halves and keep the DNA molecules separated (they are needed because the sides are attracted to each other and with out

Scientist compares the DNA to make sure that their looking for the right person and not to make any mistakes. Scientists extract the DNA when they use blood‚ saliva‚ and other body fluids and tissues. For example the crime investigators

The DNA double helix model In 1953 James Watson and Francis Crick made a scientific breakthrough when they discovered the structure of DNA. From this structure they inferred that DNA contains information written in a genetic code‚ is passed from one generation to the next. This discovery was to be a key step in the genetics revolution DNA has four molecular building blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C). Purine base always pairs (by hydrogen bonding) with
