DNA vs. RNA – 5 Key Differences and Comparison
Jan 22, 2024 · What are the three types of RNA? Messenger RNA (mRNA) copies portions of genetic code, a process called transcription, and transports these copies to ribosomes, which are the cellular factories that facilitate the production of proteins from this code.Transfer RNA (tRNA) is responsible for bringing amino acids, basic protein building blocks, to these protein factories, in response to the coded ...
Essential Amino Acids: Chart, Abbreviations and Structure
Dec 18, 2023 · Amino acids are the building blocks that form polypeptides and ultimately proteins. Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein synthesis, tissue repair and nutrient absorption. Here we take a closer look at amino acid properties, how they are used in the body and where they come from.
Cation vs Anion: Definition, Chart and the Periodic Table
Jan 24, 2024 · Metallic atoms hold some of their electrons relatively loosely. Consequently, they tend to lose electrons and form cations. Conversely, most nonmetallic atoms attract electrons more strongly than metallic atoms, and so gain electrons to form anions.
Prokaryotes vs Eukaryotes: What Are the Key Differences?
Jun 26, 2024 · Every living organism falls into one of two groups: eukaryotes or prokaryotes. Cellular structure determines which group an organism belongs to. In this article, we will explain in detail what prokaryotes and eukaryotes are and outline the differences between the two. <br /><br />
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 ...
SEM vs TEM - Technology Networks
Jan 24, 2024 · Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) are the two most common types of electron microscopy. TEM and SEM differ in how they work and what types of images they are able to capture. This article will overview SEM and TEM, including what they are, how they work, and how they compare to one another.<br /><br />
Active vs Passive Immunity: Differences and Definition
Dec 18, 2023 · Immunity is made up of both innate and adaptive arms. Innate immunity, also known as natural or genetic immunity, is something an organism is born with, encoded in their genes and protects them throughout their life.Innate immunity consists of: External defenses: Known as the first line of defense, external defenses work to protect an organism from pathogen exposure and include things like the ...
NMR Spectroscopy Principles, Interpreting an NMR Spectrum and …
Feb 22, 2024 · Nuclear magnetic resonance (NMR) spectroscopy is a physicochemical technique used to obtain structural information about molecules. It is based on the physical phenomenon of magnetic resonance that was first demonstrated by Isidor I. Rabi in 1938.
UV-Vis Spectroscopy: Principle, Strengths and Limitations and ...
Dec 18, 2023 · 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 data, the technique's strengths and limitations ...
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 ...
