AP Bio Unit 6 DNA Replication

Replicate the following strand of DNA: 
AATCATGGA

• AATCATGGA

• TTAGTACCT

• UUAGUACCU

• GGATAUCUA

DNA replication results in two DNA molecules,

• each one with two original strands

• each one with two new strands

• each one with one new strand and one original strand

• one with two new strands and the other with two original strands

What is the correct complimentary strand for the following DNA?ATCGAG

• TACGAG

• ATCGAG

• TAGCTG

• TAGCTC

Why is DNA important?

• it is very small and very complicated

• it's in everything

• it serves as the blueprint for traits of all living things

• because we eat it every day for energy

What are the 4 nitrogen bases?

• adenine, thymine, cytoplasm, and guanine

• adenine, thymine cytosine, and guanine

• adenine, thymine, cytosine, and gylcerol

• adenine, thymine, cytosine, and glucose

The term used to describe DNA Replication is:

• Semi-Conservative

• Conservative

• AntiParallel

• Dispersive

The process of DNA replication is called semi conservative because it results in

• none of these

• Two DNA molecules.  One original molecule and one with two new strands

• two exact copies with new strands

• two identical molecules, each with 1 original strand and one new.

Which enzyme seals okazaki fragments together on the lagging strand?

• Topoisomerase

• Helicase

• Polymerase

• Ligase

The 5' end of DNA is marked by a(n)

• Phosphate Group

• Hydroxyl Group

• Purine

• Pyrimidine
