Aliun [14]

Answer:

The correct answer is option d. "The phospholipids in this procedure had a shorter average fatty acid tail length than in the original experiment".

Explanation:

One factor that affects the speed at which fluorescent proteins achieve an even distribution is the length of the average fatty acid tails. Cell hybrids are produced by the fusion of two cells, which means that the genomic content of each cell must surpass the cell membrane barrier. The shorter the average fatty acid tails of the phospholipids in the cell membrane are, the faster the cell fusion will occur and the faster the fluorescent proteins will achieve an even distribution.
