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.
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 ...
Prokaryotes vs Eukaryotes: What Are the Key Differences?
Jun 26, 2024 · 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
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.
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 ...
Missense, Nonsense and Frameshift Mutations: A Genetic Guide
Apr 26, 2022 · A missense mutation occurs when there is a mistake in the DNA code and one of the DNA base pairs is changed, for example, A is swapped for C. This single change means that the DNA now encodes for a different amino acid, known as a substitution. Sometimes a change in the amino acid has no effect on the resulting protein's function at all.
Study Reveals DMT’s Effects on the Human Brain in …
Mar 27, 2023 · A new study has unveiled how psychedelics achieve their perception-altering effects in the human brain. The research used a powerful combination of brain analysis techniques to provide the clearest picture yet of how the short-acting, but powerful psychedelic DMT (dimethyltryptamine) affects brain activity.The research was published in the journal PNAS.
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 ...
IR Spectroscopy and FTIR Spectroscopy: How an FTIR …
Apr 12, 2024 · 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).
Gray Matter vs White Matter - Technology Networks
Jan 24, 2024 · 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.
