Question

These all pertain to the west nile virus. Please help!!

(2 points) If you noticed as we went through the sequences some are whole genome sequences, where as others are partial genome sequences, or a specific glycoprotein sequence. How is it that we are able to make comparisons from these sequences if they all have different lengths?’

(2 points) How many distinct lineages are defined by this tree? What does this tell us about the lineages and the locations of their outbreaks?

(2 points) The virus coded JE SA 14 is an encephalitis virus. Why did we include it on our tree?

Explanation / Answer

For similarity matching of sequences, the two sequences may not be of same length but matching of sequences should have some lengths that are comparable. depending on that similarity only the tree are generated the more similar are closer to each than other.

On basis of the given phylogenetic tree we can draw following conclusions: JESA14 are evolutionally highly prominent and not likely to be similar to other and deviated at earliest from others. Wn israel are closer to Wn morocco and WN senegal and WN c is dervied from Wn nigeria.

West Nile virus is an arbovirus of the Flavivirus kind in the family Flaviviridae and encephalitis virus (JEV) itself is a virus from the family Flaviviridae, thats is the reason they are taken for tree.
