Do dna primers add onto the lagging strand
WebBoth strands of DNA are used in its replication. Since the two strands have polarity and are anti-parallel, one strand can be continuously synthesized (the leading strand) whereas, the other strand is discontinuously synthesized (the lagging strand) which is later stitched together with ligases. Manju Rhekha MBBS student 😁🩺 1 y Sally Gloriana Webdna polymerase i only works on extending the Okazaki fragments on the lagging strand dna polymerase i Primary job is to fill in the gaps as RNA primers are removed; Same proofreading capability as DNA pol III Rnase H removes all RNA except last RNA nucleotide dna polymerase i removes the last DNA nucleotide ligase
