Laxu's answer made no sense so I deleted it. Next time Laxu please contribute something that makes some grain of sense.
Only RNA primers can be used because DNA polymerase cannot add nucleotides without an existing 3-OH' to build on. RNA can be added to an existing template without this requirement and is then used by the DNA polymerase to initiate the strand.
What else can I help you with?
Is origin of replication or replication fork same?
No, the origin of replication is a specific sequence of DNA where the replication process starts, while the replication fork is the Y-shaped structure formed during DNA replication where the DNA strands are unwound and replicated. The origin of replication initiates the formation of the replication fork.
Theta mode of replication in colE1 plasmid?
In the theta mode of replication in ColE1 plasmid, replication initiates from a single origin of replication called oriV. The replication machinery creates two replication forks that move in opposite directions around the circular DNA molecule, leading to the formation of two daughter plasmids. This mode of replication is common among small plasmids in bacteria and involves the formation of a theta structure resembling the Greek letter theta.
How does the structure of chromosomes in prokaryotic cells and eukaryotic cells affect the DNA replication processes in a cell?
In prokaryotic cells, which have a single circular chromosome, replication initiates at a single origin of replication and proceeds bidirectionally until the entire chromosome is copied. In contrast, eukaryotic cells have multiple linear chromosomes that replicate from multiple origins of replication simultaneously. The linear nature of eukaryotic chromosomes poses challenges during replication, such as the need to overcome end-replication problem and preserving telomeres.
What role does the primase play in replication?
Primase is the enzyme responsible for synthesizing short RNA primers that provide a starting point for DNA synthesis by DNA polymerase during DNA replication. These primers serve as a foundation for the attachment of nucleotides that will form the new DNA strand. In essence, primer synthesis by primase initiates the replication process by allowing DNA polymerase to extend the primer with new DNA nucleotides.
What is the difference between primer and promotor in cell biology?
In cell biology, a primer is a short piece of RNA or DNA that is required for initiating DNA replication, while a promoter is a region of DNA that initiates the transcription of a particular gene. Primers are needed for DNA replication, while promoters are needed for gene transcription.
Is origin of replication or replication fork same?
No, the origin of replication is a specific sequence of DNA where the replication process starts, while the replication fork is the Y-shaped structure formed during DNA replication where the DNA strands are unwound and replicated. The origin of replication initiates the formation of the replication fork.
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
What is the importance of replication?
It is only because of replication that the generation continues.

What kind of molecule is primase?
Primase is an enzyme. It is used to synthesize a short RNA fragment called a primer during DNA replication.
Is it free to join The Initiates Program?
Yes, it is free. The only cost to you is the time you put into it.
Who is the leader of The Initiates Program?
The leader of The Initiates Program is Jsarino.
What is the abbreviation of The Initiates Program?
The abbreviation of The Initiates Program is TIP.
How do you know if it's a breakup or just a break?
The only way to find out is to ask the person who initiates the breakup.
What system initiates movement first?
the nervous system initiates movement first
