DNA Replication

Replicate the following strand of DNA: 
AATCATGGA

• AATCATGGA
• TTAGTACCT
• UUAGUACCU
• GGATAUCUA

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

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

The bonds that hold the two strands of DNA together come from...

• the attraction of phosphate groups 
• strong bonds between  bases and sugars
• carbon to carbon bonds in the sugar
• weak hydrogen bonds between the bases

The DNA nucleotide is composed of three parts. Which two components make up the nucleotide backbone?

• ribose sugar and base
• ribose sugar and phosphate group
• nitrogen base and deoxyribose sugar
• deoxyribose sugar and phosphate group
  

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
