AP Biology Replication

The concept that DNA is made of two strands running in opposite directions is called:

• Antiparallel

• Isomerism

• Enantiomerism

• S/R Chirality

Who's work concluded that the %A=%T  and %G=%C

• Chargaff

• Meischer

• Levene

• Hammerling

This enzyme joins fragments of the lagging strand.

• DNA polymerase

• Helicase

• Ligase

• RNA Polymerase

• Topoisomerase

This is a short stretch of RNA that is used to start a complementary strand of DNA during replication.

• Liger

• Primer

• Okazaki fragment

• Initiator

A new strand of DNA is created in the ____ direction during DNA replication.

• 3' to 5'

• 5' to 3'

Each daughter DNA molecule is composed of...

• one original strand and one new strand

• two new strands

• two original strands

The difference in the way that the leading and lagging strands are made is a result of...

• DNA polymerase

• Helicase

• Ligase

• RNA Polymerase

• Topoisomerase

DNA polymerase moves toward the replication fork when creating the _____ strand

• leading

• lagging

Of the folloiwng choices, the difference in the way that the leading and lagging strands are made is best attributed to...

• the antiparallel nature of the DNA strands

• the inability to create more than one primer

• the inability of helicase to work in either direction

During DNA replication what is the first process to occur?

• Synthesis of the lagging strand

• Unwinding of parental DNA

• Synthesis of the lagging strand

• Sealing of the nicks between short DNA sections
