Is Aminoacyl tRNA Synthetases rna or dna

DNA polymerases and aminoacyl-tRNA synthetases (ARSs) represent large enzyme families with critical roles in the transformation of genetic information from DNA to RNA to protein.

Explanation:

DNA polymerases and aminoacyl-tRNA synthetases (ARSs) represent large enzyme families with critical roles in the transformation of genetic information from DNA to RNA to protein.

Explanation:

Aminoacyl-tRNA synthetases (aaRS) play a central role in protein biosynthesis by catalyzing the attachment of a given amino acid to the 3' end of its cognate tRNA. They do this by forming an energy-rich aminoacyl-adenylate intermediate of the cognate amino acid, which serves to transfer the amino acid to the tRNA.

wait any answer choices plz

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
