What Elements Are Analysed in Fuel?Request information Typical crudes are made up of 84.5% carbon, 13% hydrogen and up to 3% sulphur, as well as small percentiles of oxygen, nitrogen, salts and metals. While all fuel types share similar molecular structures, physical properties can vary hugely...
Many genes that are carried by mobile elements code for traits that are expressed outside of the cell. Such traits are involved in bacterial sociality, such as the production of public goods, which benefit a cell's neighbours, or the production of bacteriocins, which harm a cell's neighbours...
The PcG and TrxG proteins are recruited to cis-regulatory elements called Polycomb/Trithorax response elements (PREs). The PcG and TrxG proteins act antagonistically through PREs to maintain silent and active gene expression states, respectively. These states are initiated by transcription factors that...
are created like regular fragment libraries, but they have adaptor tags on both ends of the DNA insert that enable sequencing from two directions. This methodology makes it easier to map reads and can be used to improve detection of g...
Atom examples include single particles of the elements of the periodic table, such as sodium, uranium, argon, and chlorine. What Makes Something an Atom? The building blocks of atoms are positively charged protons, neutral neutrons, and negatively charged electrons. Protons and neutrons are similar...
