Front

Which of the following is a circular DNA from bacteria that can hold a foreign gene?

Back

plasmid

Front

Which protein acts as DNA scissors?

Back

restriction enzyme

Front

Which enzymatic protein acts as DNA glue?

Back

ligase

Front

Which of the following is a complicated series of steps that make proteins from coded instructions in DNA?

Back

protein expression

Front

Which is true about plasmids?

Back

All of the statements are true about plasmids.

Front

A restriction enzyme is used to cut both the gene of interest and the plasmid at the restriction sites.

Back

True

Front

In bacteria, restriction enzymes are used for defense. They cut up the DNA of a virus that infects bacteria.

Back

True

Front

Once the gene and plasmid have been cut with a restriction enzyme, another enzyme is used to join the pieces of DNA together.

Back

ligase

Front

Which model organism is often used in rDNA technology to make insulin?

Back

E. coli

Front

What are the steps of recombinant DNA technology using bacteria?

Back

Plasmid & genes are cut → cut DNA joined with ligase to make rDNA plasmids → rDNA plasmids are inserted into the bacteria → bacteria & rDNA plasmid multiply → bacteria are broken open & protein is collected
