Answer 1

Answers

1. In electrophoresis, DNA will migrate towards anode or positive electrode in TAE buffer. Because DNA is a negatively charged molecule so it moves to positive.

2. The majority of monosaccharides are found in the human body are of D-type.

3. The answer to this is fructose because it gives positive on reducing sugar test and negative in glucose oxidase test.

Then as it is monosaccharide it is not cleaved by acid.
