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.
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 ...
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.
Cell Potency: Totipotent vs Pluripotent vs Multipotent Stem Cells
WEBMay 29, 2018 — Differentiate into cells from any of the three germ layers. 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.
UV-Vis Spectroscopy: Principle, Strengths and Limitations and ...
WEBJun 30, 2021 — Ultraviolet-visible (UV-Vis) spectroscopy is a widely used technique in many areas of science ranging from bacterial culturing, drug identification and nucleic acid purity checks and quantitation, to quality control in the beverage industry and chemical research. This article will describe how UV-Vis spectroscopy works, how to analyze the output …
Active vs Passive Immunity: Differences and Definition
WEBMay 20, 2020 — 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 …
How Subliminal Images Impact Your Brain and Behavior
WEBJan 26, 2021 — 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 …
IR Spectroscopy and FTIR Spectroscopy: How an FTIR …
WEBAug 16, 2022 — The human eye can only see a small part of the much broader spectrum of electromagnetic radiation (Figure 1). On the high-energy side of the visible spectrum lies the ultraviolet (UV) region, while on the lower energy side is the infrared (IR).
An Introduction to Culturing Bacteria | Technology Networks
WEBNov 9, 2021 — Bacteria are an important part of the production of many foods and are broadly split into probiotics and starter cultures. Probiotics are generally cultured for their benefit to human health, 18 often through our gut microbiome. While probiotics may contain many different bacterial species, Lactobacillus and Bifidobacterium are common choices ...
Gray Matter vs White Matter | Technology Networks
WEBAug 20, 2019 — Gray matter is made up of neuronal cell bodies, while white matter primarily consists of myelinated axons. In the brain, white matter is found closer to the center of the brain, whereas the outer cortex is mainly grey matter. The reverse is true in the spinal cord, which has a grey matter-lined interior with white matter on the outside.
