Genetic Engineering

Question 1

Name 5 key words/phrases for the topic of genetic engineering:

Answer 1

• DNA restriction enzyme
• Sticky ends
• DNA ligase enzyme
• Recombinant DNA
• Vector

Question 2

What does the DNA restriction enzyme do?

Answer 2

It cuts specific genes from chromosomes. The same one is also used to cut open plasmids.

Question 3

What are sticky ends?

Answer 3

Each DNA restriction enzyme cuts at a specific sequence of bases, producing short single stranded sections called sticky ends.

Question 4

What does DNA ligase enzyme do?

Answer 4

It forms bonds between the nucleotides to stick both pieces of DNA together.

Question 5

What is recombinant DNA?

Answer 5

A combination of DNA from 2 different sources.

Question 6

What is a plasmid/ virus carrying the human DNA referred to as?

Answer 6

A vector - it can insert the recombinant DNA into other cells.
