NEETBiologyMolecular Basis of InheritanceMCQ+4 / −1
Which of the following reunites the exon segments after RNA splicing ?
  1. A
    RNA polymerase
  2. B
    RNA proteases
  3. C
    RNA primase
  4. D
    RNA ligase
View written solutionFree

Correct answer: D

RNA polymerase enzyme catalyses the synthesis of RNA. It is single in prokaryotes. There are three types of RNA polymerases in eukaryotes– I for 28S, 18S and 5.8S RNA, II for mRNA and snRNA and III for tRNA, 5S RNA and scRNA. Primase is an RNA polymerase that is used to initiate DNA synthesis. RNA ligase reunites the exon segment after RNA splicing.
