A vector is a segment of DNA that can kill the desired gene or gene fragment in a bacterium.

True
False
Question 2 2 points Save
The agarose gel can separate DNA fragments of different lengths because smaller DNA segments move faster toward the charged pole and the larger ones move slower.

True
False
Question 3 2 points Save
Gel electrophoresis is a technique that allows the DNA fragments to separate according to length.

True
False
Question 4 2 points Save
Restriction enzymes are not sequence specific in that they do not recognize and bind specific DNA sequences.

True
False
Question 5 2 points Save
The positively charged DNA molecules flow to the negatively charged poles in the electrophoresis chamber.

True
False
Question 6 2 points Save
The purpose of ethidium bromide is to bind to the DNA double helix and to glow when exposed to ultraviolet light to tell the scientist where the DNA fragments end up.

True
False
Question 7 2 points Save
In the scientific method, the hypothesis phase is where one or more falsifiable explanations for the observation are developed.

True
False
Question 8 2 points Save
In the scientific method, the observation phase is defining the problem you wish to explain.

True
False
Question 9 2 points Save
A map of restriction enzymes can be generated by cutting DNA with different combinations of restriction enzymes.

True
False
Question 10 2 points Save
Restriction enzymes produce DNA fragments cut at specific base sequences.

True
False

Explanation / Answer

Please rate - Thanks 1. False --- A vector does not kill a host. It exists in the host and in some cases the protein it encodes may kill the host. 2. True -- 3. True -- 4. False -- restriction enzymes _are_ specific 5. False -- Nope. The DNA is highly negative 6. True 7. True 8. False 9. True 10. True
