What is the nucleotide that RNA uses instead of thymidine ("T")? What are the subunits (monomers) of nucleic acids such as DNA and RNA? A) sugar B) hydrogen bonds C) nucleotides D) amino acids What is the monomer of nucleic acids?
When the phosphate group is covalently attached to the pentose sugar, it forms a nucleotide. Nucleotide (biochemistry) The monomer constituting DNA or RNA biopolymer molecules. Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or...
Stem cells are one of the foundational evolutionary novelties that allowed the independent emergence of multicellularity in the plant and animal lineages. In plants, the homeodomain (HD) transcription factor WUSCHEL (WUS) is essential for the maintenance
Phytoplankton are key components of the oceanic carbon and sulfur cycles1. During bloom events, some species can emit large amounts of the organosulfur volatile dimethyl sulfide (DMS) into the ocean and consequently the atmosphere, where it can modulate aerosol formation and affect climate2,3. In...
(iii) β-actin monomer is a subunit of the BAF complex, bound to BRG1 (Zhao et al., 1998); (iv) PI(4,5)P2 promotes actin filament binding, relieving capping of BAF53 and actin by BRG1 terminus; (v) BAF complex can be located at the nuclear matrix by PI(4,5)P2; (vi) BAF ...
Since many of the protein product sequences for the newly described genes, including ScyD, ScyE, and ScyF, have export signal domains, while others have putative transmembrane domains, it can be inferred that scytonemin biosynthesis is compartmentalized within the cell. Basic structural monomer ...
They are functional as homotetramers, with each monomer encoding one single stranded DNA binding domain (OB-fold). The fluorescence titrations indicated that the length of the ssDNA-binding site size is approximately 30 ± 2 nucleotides for the Pin SSB, 31 ± 2 nucleotides for the ...
Structure determination of MCLC The recombinant MCLC was purified from E. coli cell extracts. During gel filtration MCLC eluted at a molecular weight of 228 ± 15 kDa. This is consistent with a previously reported hexameric oligomerization state [9], because one monomer of the recombinant enz...
Compound 22 (remdesivir, GS-5734) is the Sp isomer of the 2-ethylbutyl l-alanine phosphoramidate prodrug and effectively bypasses the rate-limiting step of 21 monomer phosphorylation [104]. Compound 22 is activated more rapidly than 21 in human cells infected with SARS-CoV and MERS-CoV, and...
Designing proteins with improved functions requires a deep understanding of how sequence and function are related, a vast space that is hard to explore. The ability to efficiently compress this space by identifying functionally important features is extremely valuable. Here we establish a method called...
