Why did President Woodrow Wilson enter World War I?
After many years of restraining from entering the war, President Wilson decided to join the Allies against the Central Powers because of a couple of main reasons. First, in 1915, there was the sinking of the RMS Lusitania by the Germans which had American passengers on board that passed away. The other main reason was the Zimmerman telegram of 1917. This was a telegram sent from Germany to Mexico asking Mexico to join the Central Powers and invade the USA if the Central Powers were to win the war. This telegram was intercepted by the British so Americans caught on to the Germans' plan before it was enacted.
What are the building blocks of DNA?
The building blocks of DNA are called nucleic acids. There are four nucleotide bases associated with DNA; adenine (A), cytosine (C), guanine (G), and thymine (T). These pair up with each other during replication to create the double helix DNA strand. Guanine and cytosine pair up on the strand leaving thymine and adenine to pair up with each other.
