DNA vs. RNA – 5 Key Differences and Comparison
Jan 22, 2024 · 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.
GC-MS Principle, Instrument and Analyses and GC-MS/MS
Feb 16, 2024 · 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 ...
Cation vs Anion: Definition, Chart and the Periodic Table
Jan 24, 2024 · 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 ...
How Subliminal Images Impact Your Brain and Behavior
Aug 24, 2022 · However, there is evidence dating all the way back all the way to the 1960’s, which suggests that showing subliminal images improves behavioral performance. Though the behavioral change has been established through multiple publications, we still don’t know how the brain processes subliminal images. Sorin Pojoga, a member of Valentin Dragoi ...
Cell Potency: Totipotent vs Pluripotent vs Multipotent Stem Cells
Dec 18, 2023 · Differentiate into a limited range of cell types. Terminology. Toti = Whole. Pluri = Many. Multi = Several. Examples. Zygote, early morula. Embryonic stem cells, Induced pluripotent stem cells. Hematopoietic stem cells, neural stem cells, mesenchymal stem cells.
LC-MS – What Is LC-MS, LC-MS Analysis and LC-MS/MS
Jul 30, 2024 · 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.
Genotype vs Phenotype: Examples and Definitions
Sep 12, 2022 · Understanding the relationship between a genotype and phenotype can be extremely useful in a variety of research areas. A particularly interesting area is pharmacogenomics.Genetic variations can occur in liver enzymes required for drug metabolism, such as CYP450.Therefore, an individual’s phenotype, i.e. their ability to metabolize a specific drug, may vary depending on which form of the ...
Active vs Passive Immunity: Differences and Definition
Dec 18, 2023 · Active immunity is defined as immunity to a pathogen that occurs following exposure to all or part of that pathogen. When the body is exposed to a novel disease agent, a cascade of signaling molecules and action from the innate immune system results in activation of the adaptive immune system. Production of large numbers of T cells and B cells ...
Cell Culture Basics: Equipment, Fundamentals and Protocols
Jan 24, 2024 · To conduct research requiring cell culture work and to perform fundamental cell culture protocols, there are several key pieces of equipment and some basic reagents that are required, summarized in Tables 1 and 2. Table 1: Basic equipment required for cell culture.3,4 Images created with BioRender.com.
An Introduction to Capillary Electrophoresis: Theory, Practice and ...
Sep 19, 2023 · The origins of these techniques (Figure 1) can be traced to the early development of electrophoresis in the 1930s by the Swedish biochemist Arne Tiselius. 1 In the 1950s, scientists, including the Swedish biochemist Stellan Hjert é n, introduced the use of chromatographic capillary tubes to the electrophoretic techniques in response to a need to use smaller amounts of sample and improve ...
