<div>Dear All</div>
<div>I am working in a project to compare the genomes of two Vibrio cholerae pandemic strains ElTor N19661 and Classical O395. During the course of this project, I am required to identify genes that are present in the leading and lagging strands. I have gone through papers and found that identification of the strands is based on their GC skew. I have interpreted as that when the GC skew is positive, the corresponding base pair positions are genes coding from the leading strand. When the GC skew is negative, it corresponds to the lagging strand. I have considered the graphs that are present in the Oriloc website for this interpretation. I would be glad if you can tell me whether this interpretation is correct. I am also interested to know about the role of the identification of “Origin of Replication” and its role in identifying the leading and lagging strand.<br>
