Question

What charge does a DNA molecule have?
1.positive
2.Negative
3.Neutral
4.Polar​

Answer 1

Answer:

DNA does contain in its backbone phosphates. These are negatively charged. This negative charge is responsible for the whole DNA molecule to appear negatively charged as a mild acid.

Answer 2

negative charge

DNA does contain in its backbone phosphates. These are negatively charged. This negative charge is responsible for the whole DNA molecule to appear negatively charged as a mild acid. So it is called* a nucleic ACID, a "DNacid".

DNA has a negative charge due to the negative charge of its phosphate component. The other two components of DNA consist of a 5-carbon sugar and a nitrogen base. The phosphate are found in the ribose-phosphate backbone of DNA. ... Because of their negative charge, DNA and RNA will move towards the positive phase.
