Question

functions of topoisomerase ,isomerase ,dna ligase ,dna polymerase I,II,III ,primase , capping , tailing,splicing,​

Answer 1

Answer: dna ligase is the enzyme for joining 2 dna fragments. It is also called molecular glue

DNA polymerase 1, II and III are enzymes helping inthe replication of DNA. It is an highly efficient enzyme with proof reading mechanism and 5'to3' exonuclease activity

Primase is the enzyme for producing RNA primer

Capping, tailing and splicing are post transcriptional modification

Capping is the addition of a guanine monophosphate to the 5' end of the mRNA produced by transcription using an enzyme called guanyl transferase to protect it from the activity of 5'-3'exonuclease

Tailing is the addition of 200 adenine moiety to the 3' end of the mRNA to protect it from 3'to 5' exonuclease

Explanation: splicing is the cutting of non coding introns and joining the exons together. It require splisosome
