Lecture Quiz 2

A  occurs within the mitochondria

B  glucose is decarboxylated producing 4 molecules of CO2

C  there is a net production of 4 molecules of ATP

D  glucose is converted into two molecules of pyruvate

E  ATP is formed by oxidative phosphorylation

A  at the origin of replication, helicase unwinds the helix and separates the bases

B  on the other side, DNA polymerase attaches complementary bases in short segments as it moves toward the replication fork forming the lagging strand

C  DNA polymerase , moving toward the replication fork, attaches complementary bases to the template strand continuously to form the leading strand

D  the (Okazaki) fragments are then linked together by DNA ligase

E  the point of separation is called the replication fork

A  FALSE

B  TRUE
