In their 1953 Nature publication‚ Watson and Crick announced their landmark discovery: DNA exists in the form of a right handed‚ three-dimensional double helix. They described their DNA model as two DNA strands connected by hydrogen bonds between complementary bases. Adenine bases are always paired with thymines‚ and cytosines are always paired with guanines. Watson and Crick identified the anti-parallel configuration of DNA strands; each 5’ end of one strand is paired with the 3’ end of its complementary

Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth’s atmosphere and that of other planets is studied. Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It can be defined as the study of the sources‚ reactions‚ transport‚ effects‚ and fates of chemical species in the air‚ soil‚ and water environments; and the effect of human activity on these. Environmental chemistry is an interdisciplinary

What would you do if the phenomenal discovery that you made wasn’t even known as your revelation at all? Unfortunately‚ this happened to me. Despite all of my hard work‚ I was given no credit until recently. I‚ Rosalind Franklin‚ discovered something so fundamental that it has led to a study that could save thousands of lives. To understand how important this is‚ you must know where I started‚ how I made the discovery‚ and what this really all led to. When I was born on July 25‚ 1920

Bellamar Caves are a National Monument that is located in Matanzas‚ Cuba‚ they are a set of cave with more than 23 kilometers of galleries. By the beauty of its gallery and caves‚ they were declared a National Monument. The galleries and passages of the cave started forming about 300 thousand years ago. According to the studies the caves were originally under the sea‚ part of the bat of Matanzas. While they were under sea level‚ these caves were full of water. The tectonic movements caused the area

X-ray crystallography shows that the anion is tetrahedral‚ with Mn-O distances of 1.66 Å‚ ca. 0.03 Å longer than the Mn-O distances in KMnO4.[1] It is isostructural with potassium sulfate. Synthesis[edit] The industrial route entails treatment of MnO2 with air:
