Solved In contrast to the leading strand, the lagging strand

WebA constant synthesis and supply of RNA primers should occur on the lagging strand of DNA. This is in contrast to the leading strand which has almost a single RNA primer. DNA synthesis is semi discontinuous and bidirectional: The replication of DNA occurs in 5′ to 3′ directions, simultaneously, on both the strands of DNA. WebA) Polymerase can work on only one strand at a time. B) Helicases and single-strand binding proteins work at the 5' end. C) DNA ligase works only in the 3' → 5' direction. D) DNA polymerase can join new nucleotides only to the 3' end of a growing strand. E) The origins of replication occur only at the 5' end. garthwaite nurseries derbyshireWeb3.2.
