Aneuploid, Euploid, Polyploid, Tetraploid Polyploidy is a condition in which the cells of an organism have more than one pair of \(homologous\) chromosomes. Most species whose cells have nuclei \(eukaryotes\) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes. A cell with any number of complete chromosome sets is called a euploid cell. Problem: Diploid Drosophila has eight chromosomes. Which one of the following terms should not be used to describe Drosophila with sixteen chromosomes? Justify your answer with suitable explanations.

Demonstrating the anti-inflammatory properties of extracellular vesicles derived from the microalga Tetraselmis chuii: in their latest work, Elia Di Schiavi, Antonella Bongiovanni at Consiglio Nazionale delle Ricerche and collaborators assessed the intrinsic biological properties of nanoalgosomes derived from marine microalgae Tetraselmis chuii cultures, using an optimised production protocol https://lnkd.in/e6bHU-td They demonstrated that nanoalgosomes, a novel type of EV, are efficiently taken up by cells through clathrin-dependent endocytosis and possess significant anti-inflammatory properties.

Hello everyone I'd like to share a video explaining the use of a method to evaluate the length of extra-radicular mycelium of arbuscular mycorrhizal fungi (AMF). The video was produced by me, with the participation of other colleagues. Research group coordinator: Prof. OSMAR KLAUBERG FILHO I hope you like it! 😃 Leave your Like on the video and follow the lab's channel on youtube Feel free to share A Portuguese version will be available soon #science #fungi #soil #ecotoxicology

“UCYN-A is, in many regards, functioning as a N2-fixing #organelle, or ‘nitroplast.’ It also shares other characteristics with organelles, including an extremely reduced #genome…” 🦠 As first reported in Cell Press and at phys.org, a cross-institute team have uncovered a #symbiosis in a marine algae that hosts a stripped-down version of a Cyanobacterium to provide it with reduced #nitrogen compounds. If verified in future experiments, we could be watching evolution in near-real time, and further supporting the theories first offered by Margulis in the 1960s. 👩🏻🔬🥼 https://lnkd.in/grfpuGNm

While approximately 20,000 proteins are encoded in the human genome, these proteins can be modified in many ways to produce potentially millions of #proteoforms with different functions, half-lives, localizations, and more. Understanding the proteoform makeup of a cell, tissue, or organism may reveal the molecular underpinnings of its #biology and enable scientists to develop more effective #biomarkers and therapeutics. In our latest animation, learn how the Nautilus™ Proteome Analysis Platform is uniquely designed to enable #SingleMolecule analysis of intact proteoforms for in-depth studies that are not possible on other platforms. https://ow.ly/1P8E50Sg87u #Proteomics #UnleashTheProteome #ProteomicsRevolution #MassSpec #TeamMassSpec #Biotech
