T/Th Exam 2: Question 38
38) Which of the following statements about restriction nucleases is false ?

Recombinant DNA technology was made possible
by the discovery of restriction nucleases
•
Restriction nucleases/enzymes are bacterial enzymes that cut
“foreign” DNA at specific DNA elements (often palindromes ).
•
Bacterial DNA is safe from these enzymes because they chemically
modify those specific DNA sequences.
•
They cut by hydrolyzing the phosphodiester bonds of nucleic acids.

Sticky ends
Restriction enzymes get
their names from the
bacteria they come from.

T/Th Exam 2: Question 39
39) Which of the following statements about gel-transfer hybridization (or Southern
blotting) is false ?

M/W Exam 2: Question 1
1) Okazaki fragments are only found in eukaryotes.

M/W Exam 2: Question 10
10) Which statement is false?
A. Primase is needed to initiate DNA replication on both the leading strand and the
lagging strand.
B. The sliding clamp is loaded once on each DNA strand, where it remains associated
until replication is complete.
C. Telomerase is a DNA polymerase that carries its own RNA molecule to use as a
primer at the end of the lagging strand.

More realistically, this replication occurs via
one large dynamic machine
Movies 6.4 and 6.5
