cell
C Isolation and identification variable
elements
D. All of above​

Answer 1

Process of DNA fingerprinting includes D. All of the above steps.

• DNA fingerprinting is a process that makes use of biotechnology to determine the characteristics of an individual's DNA.
• The DNA is extracted from the cell of the person and purified by subjecting the cell to various enzymes and treatment with chilled ethanol.
• The DNA strands are then cut using suitable restriction endonuclease enzymes also called molecular scissors.
• The DNA fragments are then separated using electrophoresis.
• These fragments are then isolated using a process called elution and identified.
