Which enzyme synthesizes a short RNA primer at the beginning of each origin of replication?
DNA polymerase III can add nucleotides only to a chain of nucleotides that is alreadypaired with the parent strands. Hence, DNA polymerasecannot link the first nucleotides in a newly synthesizedstrand. Instead, another enzyme, an RNA polymerasecalled primase, constructs an RNA primer, a sequence ofabout 10 RNA nucleotides complementary to the parentDNA template. DNA polymerase III recognizes the primerand adds DNA nucleotides to it to construct the new DNAstrands. The RNA nucleotides in the primers are then replacedby DNA nucleotides.
For DNA polymerase to link nucleotides together as new strands of DNA the first nucleotide must be attached to what because DNA polymerase can only add nucleotides to a pre exsisting strand?
The first nucleotide must be attached to a short RNA primer to provide a free 3' hydroxyl group for DNA polymerase to extend from. DNA polymerase starts adding nucleotides to this RNA primer to begin DNA replication.
What does the first nucleotide attach to because DNA polymerase can only add nucleotides to a pre-existing strand?
A primer molecule is required for DNA polymerase to initiate the addition of nucleotides. This primer provides a starting point for DNA polymerase to begin adding nucleotides in the correct sequence. Once the primer is in place, DNA polymerase can add nucleotides complementary to the template strand.
What is a RNA primer removed by?
A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
Which of the following removes the RNA nucleotides from the primer and adds equivalent DNA nucleotides to the 3' end of Okazaki fragments?
DNA polymerase I removes the RNA nucleotides from the primer and adds equivalent DNA nucleotides to the 3' end of Okazaki fragments in prokaryotes.

Why only RNA primer provide 3-OH' end for DNA replication?
The reason you only need RNA primer at the end to make a DNA replication is because it has a free 3' OH. RNA is ribonucleic acid. RNA contains long chains of nucleotides.
During DNA duplication primer called RNA primer why?
During DNA duplication, an RNA primer is used because DNA polymerase can only add new nucleotides to an existing nucleic acid strand rather than initiating synthesis. The RNA primer provides a starting point for DNA polymerase to bind and begin adding complementary nucleotides to synthesize a new DNA strand. This primer is later removed and replaced with DNA nucleotides to complete the replication process.
What is a RNA primer removed by?
A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.

Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
Why RNA primers are needed during DNA replication and what is their fate?
DNA polymerase cannot begin the synthesis of new DNA.To synthesis a new strand of DNA ,RNA primer is required.The complementary RNA nucleotides,that are added opposite to the single strand of parent DNA are the RNA primer.
What primer is needed at the origin of nucleotide addition?
A primer made of RNA is required at the origin of nucleotide addition for DNA replication. This primer provides a free 3' OH group for DNA polymerase to start adding nucleotides and serves as a starting point for DNA synthesis.
Why is it called a RNA primer?
The RNA primer is referred to a short RNA fragment into which are added deoxyribonucleotides by DNA polymerase III during DNA replication. The primer stimulates the synthesis of the new chain by participating in the initiation of polymerization of the desoxyribonucleotides. In nucleic acid chemistry, a primer can be a short, either single-stranded RNA or DNA, segment that functions as the starting point for the polymerization of nucleotides.
What enzyme Cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides?
The enzyme that cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides is DNA polymerase I in prokaryotes and DNA polymerase delta in eukaryotes. This process, known as primer removal or primer excision, is essential for completing DNA replication accurately.
