The resulting DNA fragments are then ligated to technology-specific adaptor sequences, forming a fragment library. These adaptors may also have a unique molecular “barcode”, so each sample can be tagged with a unique DNA sequence. This...

Atomsare the foundation of matter, which is everything that makes up the universe around us. Each kind of atom makes up a pure substance called an element. You may have heard of oxygen, lead, and gold. Well, these are all examples of elements. Can you believe that a pure gold ...
Elements are the building blocks of chemistry and matter. Each element is defined by the number of protons in its nucleus. The chemical elements are organized on theperiodic table of the elements. Each element has an atomic number and a symbol. The symbol may be based on the Latin name of...
What are the elements that make up the majority of the human body?(Image credit: metamorworks via Getty Images) There are 118 elements on theperiodic table, and you might think we are made up of many of them. But that's not the case; the complex systems that make up our bodies have...
Magnesium oxide (chemical formula: MgO) is a compound composed of magnesium and oxygen elements. Relative molecular mass is the ratio of the mass of a substance molecule to the mass of carbon-12 isotope. It can be used to describe the size of the Magnesium oxide molecule's mass. What ...
While we lost the heir apparent to the "fundamental building block" we got consolation prizes in terms of an understanding of the periodic system of elements and their chemical properties as well as understanding of atomic and molecular spectra. It then seemed that the photon, the electron, the...
What are chiral carbons and why do they lead to isomers? Deduce if the following molecule is chiral or achiral. Can you help me understand why there is only one chiral ketone that has the molecular formula C6H12O? Define what is constitutional isomers?
