Cation vs Anion: Definition, Chart and the Periodic Table
WEBAug 15, 2019 · Cation vs anion periodic table. It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form ...
DNA vs. RNA – 5 Key Differences and Comparison
WEBDec 18, 2020 · DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be several centimetres in length when unraveled. RNA molecules are variable in length, but much shorter than long DNA polymers. A large RNA molecule might only be a few thousand base pairs long. Sugar.
Prokaryotes vs Eukaryotes: What Are the Key Differences?
WEBJul 8, 2021 · The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
Essential Amino Acids: Chart, Abbreviations and Structure
WEBSep 26, 2019 · What is the structure of the amino acids? An amino acid’s structure consists of a central carbon atom attached to a hydrogen, an acidic carboxyl group (−COOH), an amino group (−NH2) and an organic side chain (also called an R group). The side chain is unique in each of the 20 amino acids. Amino acid. Abbreviation.
GC-MS Principle, Instrument and Analyses and GC-MS/MS
WEBJun 10, 2022 · The sample mixture is first separated by the GC before the analyte molecules are eluted into the MS for detection. 1 They are transported by the carrier gas (Figure 1 (1)), which continuously flows through the GC and into the MS, where it is evacuated by the vacuum system (6). 1. The sample is first introduced into the GC manually or by an autosampler (Figure 1 (2)) and enters the carrier gas ...
LC-MS – What Is LC-MS, LC-MS Analysis and LC-MS/MS
WEBMay 17, 2021 · Coupling liquid chromatography (LC) with mass spectrometry (MS) has provided scientists with a powerful tool to meet stringent analytical demands and their versatility and efficiency means LC-MS instruments have become desirable in many laboratories. In this article, we consider how LC-MS works, what it tells us and highlight some of the technique's strengths and weaknesses.

Humoral vs Cell-Mediated Immunity | Technology Networks
WEBJan 25, 2021 · Humoral immunity and cell-mediated immunity are two types of an adaptive immune response that enable the human body to defend itself in a targeted way against harmful agents such as bacteria, viruses and toxins. Whilst there is some overlap between these arms of the immune response - both rely on the functions of lymphoid cells - there are also some important differences.<br />
