What does the charge of DNA have to do with DNA fingerprinting?
The charge of DNA does not directly affect DNA fingerprinting. DNA fingerprinting relies on variations in DNA sequences, not on its charge. The technique separates DNA fragments based on size and does not involve its charge.
How does DNA charge affect movement in electrophoresis?
DNA molecules have a negative charge due to the phosphate groups in their backbone. In electrophoresis, an electric field is applied across a gel matrix, causing DNA fragments to migrate towards the positive electrode. The negatively charged DNA molecules are attracted to the positive electrode and move through the gel at different rates based on their size, with smaller fragments moving faster than larger ones.
Why does DNA wraps around histone?
DNA wraps around histone proteins to form a structure called a nucleosome. This packaging allows for compaction of DNA, making it more efficient for storage in the cell. Additionally, the interaction between DNA and histones plays a role in gene regulation by influencing accessibility of DNA for transcription factors.
Why the charged balloon wiill be attracted to the charged glass rod?
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other
Cations are attracted to cathod or anode?
Cations are positively charged ions, and they are attracted to the cathode in an electrolytic cell. At the cathode, cations gain electrons and get reduced.
