Question

36 multiple choice 1 point restriction fragment length polymorphism (rflp) technique is widely used in dna fingerprinting. which of the following statements is true about rflp analysis? it recognizes a difference in the restriction patterns across individuals. it creates a difference in the restriction patterns in individuals. different restriction enzymes are used to generate polymorphisms that can be visualized in a gel. differential gene expressions generate differences that are visualized in a gel.

Explanation:

To solve this, we analyze each option:

• Option 1: RFLP analysis identifies differences in restriction patterns (from DNA cleavage by enzymes) between individuals, which is correct.
• Option 2: RFLP doesn't create patterns but detects existing differences, so this is wrong.
• Option 3: RFLP uses the same restriction enzyme (or set) for samples, not different ones to generate polymorphisms, so wrong.
• Option 4: RFLP is about DNA restriction fragments, not gene expression, so wrong.

Answer:

It recognizes a difference in the restriction patterns across individuals.
