Compare the addition of RNA nucleotides to mRNA by RNA polymerase to the addition of the CCA nucleotide to tRNA by CCA-adding enzyme. How the differences and similarities in the structures of DNA and RNA adapt them to their specific functions?

single-strand binding proteins bind the unwound DNA and prevent the double helix from re-forming transcription the promoter region acts as an initial binding site for RNA polymerasethe RNA nucleotides used are produced by the cellonly one of the DNA strands is used as the template more than one...
The activity of DNA polymerase-β, the most predominant DNA polymerase in neurons that is generally considered to be a short-patch repair enzyme, shows a significant decrease in aging neurons. Northern and Southern blotting and immunotitration experiments suggest that there may be an accumulation of...
Inactivation of the phytohormone auxin plays important roles in plant development, and several enzymes have been implicated in auxin inactivation. In this study, we show that the predominant natural auxin, indole-3-acetic acid (IAA), is mainly inactivate
Bacteriophages are a class of virus that can infect bacteria and archaea; for example, lambda phage infects E. coli. Following infection, this phage can either integrate its DNA into the genome of the host E. coli cell, or it can replicate its DNA, form new phage particles, and lyse ...
Besides vaccines, the development of antiviral drugs targeting SARS-CoV-2 is critical for preventing future COVID outbreaks. The SARS-CoV-2 main protease (Mpro), a cysteine protease with essential functions in viral replication, has been validated as an

The functions of type B cells remain enigmatic, and no sensory stimuli have been described. Molecularly, type B cells are fundamentally different from canonical OSNs and VSNs (Omura and Mombaerts, 2014, 2015; Saraiva et al., 2015), suggesting that their ligands are also fundamentally different...
Double-strand DNA breaks (DSBs) resulting from metabolic cellular processes and external factors pose a serious threat to the stability of the genome, but
