patterns
4 gene therapy d. used to separate dna fragments by size and charge
5 dna fingerprinting e. inserting a gene from one organism into another organisms
dna

Explanation:

Question 8

Recombinant DNA technology is used to create human insulin in bacteria. It involves inserting the human insulin gene into bacterial DNA. Cloning is making identical copies. Restriction enzymes cut DNA. CRISPR is for gene editing.

A clone is an organism that is genetically identical to the parent. So when a clone is created, it is exactly like the parent genetically.

• Gel electrophoresis: Separates DNA fragments by size and charge (matches d).
• Recombinant DNA: Inserts a gene from one organism into another's DNA (matches e).
• PCR: Makes many copies of a specific DNA segment (matches b).
• Gene therapy: Replaces a defective gene with a normal one to treat disease (matches a).
• DNA fingerprinting: Identifies individuals based on unique DNA banding patterns (matches c).

Answer:

a. Recombinant DNA
