Question

question 2 (1 point)
what is dna fingerprinting?
○ a) a process in which the size and order of dna segments is determined.
○ b) the technique of quickly making copies of dna using enzymes and a cyclic
fluctuation in temperature
○ c) a process used to separate fragments based on charge and size.
○ d) a technique in which dna samples are cut by restriction enzymes, and the
resulting fragments are separated via electrophoresis creating a pattern of
bands.

Explanation:

DNA fingerprinting involves determining the size and order of DNA segments. This is a fundamental aspect of the technique. Option a) correctly describes this core process. Option b) refers to PCR (Polymerase Chain Reaction) which is about making copies of DNA. Option c) is about gel - electrophoresis (separating fragments based on charge and size). Option d) also relates to gel - electrophoresis (separating fragments via electrophoresis).

Answer:

A. A process in which the size and order of DNA segments is determined.
