Why is DNA negatively charged and why is this charge important for gel electrophoresis?
DNA is negatively charged because it contains phosphate groups in its structure, which carry a negative charge. This charge is important for gel electrophoresis because the DNA molecules will move towards the positive electrode in the gel due to their negative charge, allowing them to be separated by size.

Do electrons have a Negative Charge or a positive charge?
They are ALWAYS negatively charged. If positively charged it would be a positron and not an electron.
What are the charges of sub atomic particles?
Protons - positively charged Electrons - negatively charged Neutrons - No charge
Are neutrons negatively charged?
Neutrons do not have an electrical charge, so they are considered electrically neutral. They have a neutral charge because they contain equal numbers of positively charged protons and negatively charged electrons.
Is electricity a negative charge?
A negative electrical charge occurs when you have more electrons than protons (electrons are negatively charged, and if you have more -'s than +'s the overall charge will be negative).
What is a negatively charged subatomic particle'?
electronThe electron is a negatively charged particle.
Is lighting negatively charged or positively charged?
Negatively charge
Which molecules are positively charged in electrophoresis?
In electrophoresis, positively charged molecules are known as cations. These include positively charged ions like sodium (Na⁺), potassium (K⁺), and certain amino acids or proteins that have an overall positive charge at a given pH. During the electrophoresis process, cations migrate toward the negatively charged electrode (cathode) due to the electric field applied.
Are electrons positively charged or negatively?
Negatively charged
A positively charged ion will bond with?
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
What does charge?
Electrons are negatively charged.
Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)

Are electrons a positive charge?
No, they are negatively charged.
What charge does electron?
Electrons are negatively charged.
Is a electron neutrally charged?
No, its negatively charged.
Are neutrons negatively charged?
Neutrons do not have an electrical charge, so they are considered electrically neutral. They have a neutral charge because they contain equal numbers of positively charged protons and negatively charged electrons.
