**** Update *****

Nearly complete draft illustration showing the action occurring at a DNA replication fork.

A coiled, linear DNA molecule enters from the left. A helicase attaches to it and it begins to uncoil, forming a replication fork. Once the two single strands are exposed, leading and lagging replication occurs

status V 1.0

  • Strand is entering from left
  • Strand is unwound and split to form the replication fork
  • Leading and lagging strand formation is almost complete (primer sequence missing for leading strand)
  • Replication process accurately creates to exact copies of the original double strand. This is shown by the matching base color pattern in the top (leading) and bottom(lagging) strands.
  • As part of replication process most of the base addition (and removal) steps are animated properly
Next steps
  • Modify the leading strand process to include a short priming sequence at the start of the replication process. This will be a short length of blue bases added by a primase enzyme.
  • Add labels
  • Add start/stop/reset controls
  • Consider show/hide controls for the enzymes
  • Consider retesting the strands after the are replicated.
Notes: The focus of this illustration is bidirectional (leading and lagging) pattern and the main enzymes involved. Excluded details include the binding proteins that keep the double strand separated.
