MCB 3020L Lecture Notes - Lecture 36: Intron, Snrnp, Messenger Rna
Document Summary
Relaxes supercoiling ahead of the replication fork produced as dna strands are separated by helicases; separates daughter molecules in final stages of replications. Makes covalent bonds to join dna strands; joins okazaki fragment and new segments in excision repair; seals nicked fragments. Cut dna backbone in a strand of dna; facilitate repair and insertions. Cut dna from an exposed end of dna; facilitate repair. Adds methyl group to selected bases in newly made dna. Uses visible light energy to separate uv-induced pyrimidine dimer. An rna polymerase that makes rna primers from a dna template. Rna enzyme that removes introns and splices exons together. An rna polymerase that makes rna primers from a dna template snrnp. Rna-protein complex that removes introns and splices exons together. Relaxes supercoiling ahead of the replication fork; separates dna circles at the end of dna replication. Synthesis of a complementary strand of rna from a dna template.
