Question

A scientist culture that have membrane proteins tagged with GFP and examines them using the Fluorescence Recovery After Photobleaching (frap) technique. she bleaches a small area of the membrane of one of the cells, waits, and then observes the cell again. the bleached area has filled in, indicating that

Answer 1

The bleached area filled in indicates that the tagged membrane proteins are mobile and can move within the membrane.

Step-by-step explanation:

The scientist is using the Fluorescence Recovery After Photobleaching (FRAP) technique to examine membrane proteins tagged with Green Fluorescent Protein (GFP). She bleaches a small area of the membrane of a cell and then observes the cell again. The fact that the bleached area has filled in indicates that the tagged membrane proteins are mobile and can move within the membrane.
