The gene is a promoter that is sensitive to the presence of the
sugar, galactose.

It is an origin of replication.

It is a cloning site.

It is a marker for insertion of foreign DNA into the
plasmid.

an orderly array of all the genes within an organism

a collection of vectors containing random segments of DNA

the collection of plasmids found within a single E. coli
cell

a collection of DNA fragments that collectively represents the
entire genome of an organism

DNA helicase

RNA polymerase

Reverse transcriptase

Restriction exonuclease

Sticky ends of DNA are oppositely charged and electrostatically
attracted to one another

Sticky ends contain a single-stranded segment of nucleotides
that is complementary to a target fragment’s single-stranded
end

Sticky ends refers to the phosphate group on the end of the DNA
molecule being sticky to the next nucleotide.


Sticky ends bind to all other pieces of DNA where bases jut out
from the end, as a natural repair mechanism.
