DNA Replication

If the percentage of DNA is made of 30% Thymine, what is the correct percentage of Guanine?

• 30
• 15
• 20
• 60

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

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription
