Restriction endonuclease - genetic engineering
Okazaki fragments are short DNA segments which help in the replication of DNA.
RNA polymerase is needed for constructing RNA chains from DNA genes as templates, a process called transcription.
The central dogma states that genetic information flows in the following order: DNA-RNA-Protein.
Restriction endonuclease is a cleaving enzyme which cleaves the DNA fragment of a chromosome into smaller DNA fragments and helps in recombinant DNA technology.
