chapter 12 Gene can be cloned in recombinant plasmids

Question 1

Define the definition of recombinant DNA

Answer 1

formed when combining pieces of DNA from two different sources often different species to form a single DNA molecule.

Question 2

small, cir laboratory DNA molecules that replicate (duplicate) separately from the much larger bacterial chromosome.

Answer 2

plasmid

Question 3

does plasmids are easily manipulated to carry virtual any genes , they are key tools for DNA cloning, the production of many identical copies of a target segment of DNA.

Answer 3

yes.this is very true plasmid does do the following.

Question 4

the cutting tools are bacterial enzymes

Answer 4

restriction enzymes

Question 5

restriction site

Answer 5

each of which recognizes a particular short DNA sequence

Question 6

what happens after a restriction enzyme binds to its restriction site

Answer 6

it cuts both strands of the DNA at precise points within the sequence (like a pair of highly specific molecular scissors-yielding pieces of DNA called restriction fragments)

Question 7

What will always cut the all the copies of a particular DNA molecule at the same place

Answer 7

same restriction enzyme

Question 8

complementary molecule is called a nucleic probe because…..

Answer 8

it is used to find a speciic gene or other nucleotide sequence within a mass of DNA.
