DIA [1.3K]

Answer:

Use a higher % agarose gel.

Explanation:

Agarose gels have a porous matrix. The higher the concentration of agarose, the smaller the pores, so larger DNA molecules will have more difficulty moving through the gel and they will run slower than small DNA molecules.

The higher % agarose gel has thus a better resolving power (the measurable interval between two entities -the DNA bands- is smaller). For that reason, a 2% agarose gel will allow you to differentiate better between two bands of close molecular weight, if you let the DNA fragments run long enough.

mafiozo [28]

Patty (age 7) has symptoms that include a skin rash, fever slowed growth, fatigue, and swelling in the joints. She was diagnosed as having juvenile rheumatoid arthritis.

What is juvenile rheumatoid arthritis described as?

Juvenile rheumatoid arthritis is the most common kind of arthritis in children. It is characterized by heat and discomfort and causes the joints to expand. The duration of acute arthritis can range from a few weeks or months to years or even a lifetime. It can also be persistent. IA types include autoimmune and autoinflammatory illnesses. This suggests that the immune system, which is meant to fight off viruses and pathogens, becomes confused and attacks the body's cells and tissues. The doctor can suggest blood testing for C-reactive protein and erythrocyte sedimentation rate. These blood tests evaluate inflammatory markers or markers of inflammation.
