Why do you think RNA but mot DNA catalyzes biochemical reations?

In reality, speeding up of biochemical reactions is done by enzymes which are proteins with a few exceptions where ribozymes(RNA) come into play. As enzymes are proteins and the latter are translational form of the information contained in DNA, we cannot go back so far as to say that DNA catalyzes the biochemical reactions, even though it carries the blue print which is transcribed and finally translated.
The question is for your action you may not like to give credit to your grandfather.
When you think catalyze, normally you think catalyst-- a compound that speeds up a reaction and is both a reactant and a product. If you consider this then the DNA elements can also catalyze biochemical reactions (i.e. gene activation, ubiquidylation, sumoylation, etc.). Like the first person who answered this question, the DNA never makes its way outside of the nucleus so it does not catalyze a reaction-- it is what is being acted on, unlike RNA which acts on other substances (i.e. tRNA, rRNA, siRNA, miRNA + many other RNAs). Unlike what the last person said though, RNA is not flexible-- it is actually rather brittle and unstable when compared to DNA.
The oxidized 2' carbon on each RNA nucleotide, the uracil, and the 5' cap along with the polyA tail is what I think catalyzes biochemical reactions over DNA

What catalyzes DNA synthesis?
DNA synthesis is catalyzed by enzymes called DNA polymerases. These enzymes are responsible for assembling new DNA strands by adding nucleotides to the growing chain during DNA replication.
Biochemical analysis uses similarities in as evidence for evolutionary relationships.?
DNA sequences .
What enzyme links DNA nucleotides to a growing daughter strand?
DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
What is the enzyme that unwinds the DNA from around the histone proteins?
The enzyme responsible for unwinding DNA from around histone proteins is called DNA helicase. It catalyzes the separation of the two strands of the DNA double helix, allowing access for other enzymes and proteins to interact with the DNA.
What enzyne produces a new DNA strand during DNA replication?
DNA polymerase is the enzyme responsible for producing a new DNA strand during DNA replication. It catalyzes the addition of nucleotides to the growing DNA chain, using the existing DNA strand as a template.
The enzyme that catalyzes DNA synthesis add nucleotides to the DNA molecule is called?
Primase
Which enzyme catalyzes covalent bond?
DNA ligase catalyzes the formation of a covalent bond between adjacent DNA strands. It plays a crucial role in joining DNA fragments during processes like DNA replication and repair.
What molecule catalyzes covalent bond formation between DNA?
DNA ligase catalyzes the formation of covalent bonds between nucleic acid strands, such as DNA. It acts by joining the sugar-phosphate backbone of two DNA fragments together to repair DNA damage or during DNA replication.
What catalyzes the linking together of nucleotide subunits?
Enzymes called DNA polymerases catalyze the linking together of nucleotide subunits in DNA replication. These enzymes attach new nucleotides to the growing DNA strand based on the complementary base pairing between the original template DNA strand and the new nucleotides.
Which enzymes catalyzes the elongation of a new DNA strand?
DNA polymerase catalyzes the reactions that are responsible for synthesizing new DNA strands in the 5' to 3' direction. The parent DNA strand is read in the 3' to 5' direction but the daughter strand is extended in the opposite direction.
Why is DNA polymerase a machine?
A DNA polymerase is an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand. See info at LINK.
Based on the function of dna polymerase explain why each part of the name dna polymerase make sense?
"DNA" refers to the molecule that the enzyme works on, "polymerase" indicates that it synthesizes polymers by linking nucleotides together to form DNA strands, and "ase" denotes that it is an enzyme, catalyzing the reaction. So, the name "DNA polymerase" signifies an enzyme that catalyzes the synthesis of DNA molecules by creating polymer chains from nucleotide building blocks.
What molecule catalyzes covalent bond formation between fragments of DNA?
DNA ligase catalyzes the formation of covalent bonds between fragments of DNA by joining together the sugar-phosphate backbones of adjacent DNA strands. This enzyme plays a critical role in DNA replication, repair, and recombination processes.
What catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed?
DNA polymerase catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed. This enzyme helps to link the 3' hydroxyl group of the growing DNA chain to the 5' phosphate group of the incoming nucleotide.
What is the biochemical evidence that supports evolution?
DNA
What is the biochemical evidence that supports biological evolution?
One key piece of biochemical evidence that supports biological evolution is the similarity in DNA sequences among different species. By comparing the DNA sequences of organisms, scientists can uncover evolutionary relationships and common ancestry. Additionally, the presence of vestigial structures and shared biochemical pathways among different species further support the idea of a common evolutionary origin.
What enzyme connects the new bases to the old bases in the DNA template?
The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.
