Question

Your lab was able to GFP tag actin in a cell in which the green fluorescence is photo-activated after pulsing it with a laser. You did an experiment in a crawling cell where you briefly activated the GFP-actin fluorescence at a pinpoint spot near the leading edge of the cell. Where do you predict the spot will move to? Will it stay stationary relative to the cell, move forward towards the leading edge, or move back towards the trailing edge? Explain your rationale. (5 sentences max)

Answer 1

According to the hypothesis, the spot in cells crawling would migrate towards an attractant used, the migration occurs towards attractant gradient. According to the many researchers, had proved that the ability of the cells crawling is observed that towards the chemo-attractant gradient only and responses will be recorded for every 15 minutes during the experiment.

Note: The provided answer is as per my knowledge may be or may not be 100% correct, but definitely relevant to your question thank you so much.
