Which of the following can be a characteristic of genetically modified GFP?

Enhanced stability is an important characteristic of genetically modified GFP. Modifications in the genetic code, such as substitutions or deletions in the amino acid sequence of GFP, can lead to proteins that are less susceptible to degradation. This increased stability can be particularly valuable in various applications, including research and biotechnology, where prolonged activity of the protein is needed.

In the context of protein applications, a more stable protein can maintain its functionality over extended periods and under varying environmental conditions, which is essential for experimental consistency and reliability. This characteristic also allows modified GFP variants to be used effectively in a wider range of biological studies and applications, such as in imaging and tracking cellular processes.

While altered size, increased solubility, and decreased brightness are also potential aspects of GFP modifications, the emphasis on enhanced stability is significant as it directly influences the performance and utility of the protein in practical scenarios.
