RNA PRIMASE Meaning and
Definition
-
RNA primase is an enzyme that plays a crucial role in DNA replication. It is a type of DNA-dependent RNA polymerase that synthesizes short RNA sequences known as primers. These primers serve as a starting point for DNA synthesis during DNA replication.
The process of DNA replication requires primers to initiate the synthesis of new DNA strands. RNA primase synthesizes these primers by adding RNA nucleotides one by one in a complementary manner to the DNA template strand. This creates a short RNA sequence that acts as a primer for DNA polymerase, allowing it to begin the synthesis of the new DNA strand.
RNA primase is essential to DNA replication because it provides the necessary primers on the lagging strand, which is synthesized discontinuously in small fragments called Okazaki fragments. Each Okazaki fragment requires a primer to initiate synthesis, and RNA primase is responsible for generating these primers.
In addition to its role in DNA replication, RNA primase is also involved in other biological processes, such as DNA repair and recombination. It is an indispensable component of the DNA replication machinery, working in conjunction with other enzymes and proteins to ensure accurate and efficient replication of the genetic material.

Etymology of RNA PRIMASE
The word "RNA primase" is derived from two distinct components: "RNA" and "primase".
1. "RNA" originates from the term "ribonucleic acid", which refers to a molecule involved in various biological processes, including gene expression, genetic regulation, and protein synthesis. The term "ribonucleic acid" was coined by Polish-American biochemist Phoebus Levene in 1898, combining "ribose" (the sugar component of RNA) and "nucleic acid" (referring to the class of macromolecules to which RNA belongs).
2. "Primase" is derived from the word "prime", which has its roots in Latin. The Latin term "primus" means "first" or "foremost".
