Q. Which of the following pairs is correctly matched ?
(a) Central dogma – Codon
(b) Okazaki fragments – Splicing
(c) RNA polymerase -RNA primer
(d) Restriction enzyme – Genetic engineering
Solution :
Correct option : D Restriction enzyme – 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.
