Some scientists even think it had a virus defense system; “researchers say LUCA likely housed 19 CRISPR genes, which bacteria use to slice up viral threats,” reports Quanta Magazine. DNA and RNA molecules are also built from exclusively right-handed nucleic acids.
The researchers first compared the editing efficiency of different versions of IscB when coupled with 'ωRNA,' which guides the enzyme to the right spot on the DNA. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome. Read more in Nature Methods.

Water accounts for 70 percent of a bacterium by mass; the other 30 percent includes everything else: proteins, RNA, DNA, lipids, and so on. If the technology proved successful in human beings, it would take Moderna weeks, not years, to make a new product,” wrote Catherine Elton in Boston Magazine.
With this expanded blessing, clinicians can add Biktarvy to their magazine of options to help insure these children maintain virologic repression with a treatment option that makes sense for them.” HIV-1 RNA wasn’t collected at Week 24 for two actors because of COVID-19 epidemic-affiliated study dislocation.
The central dogma is often depicted as DNA→RNA→protein, but it’s much more: A biophysical marvel inside the smallest of vessels. Asterisk Magazine 13 of 31. Eterna is an online game (there’s also an app) where anyone on the internet can solve puzzles by manipulating RNA sequences and simulating the results.
A T4 phage can hold 171,000 bases of DNA or other molecules, including proteins and RNA. It uses single-molecule RNA fluorescence to measure mRNAs and fluorescent reporters to measure the proteins. This essay , in Asterisk Magazine , is the best I’ve seen at explaining why cultivated meat is so expensive in the first place.

Link Experimental Tests of the Virtual Circular Genome Model for Nonenzymatic RNA Replication. Link U1 snRNP increases RNA Pol II elongation rate to enable synthesis of long genes. Link Gene Editing, CRISPR & Genetic Control *Targeted DNA integration in human cells without double-strand breaks using CRISPR RNA-guided transposases.
Messenger RNA is a molecule, one of the two types of nucleic acid, that carries the information that tells cells to link amino acids in a certain sequence, producing a protein. The definition of RNA is part of high school science standards. … the disease gradually travelled southward, almost stripping the country of children.

Comparison of transformations for single-cell RNA-seq data. Read Spatiotemporally resolved transcriptomics reveals the subcellular RNA kinetic landscape.
Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. ” Quanta Magazine. Stahl et al. on bioRxiv. If you want to edit a gene inside of a neuron, what do you do? Ars Technica.
