Week #8 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

A scientist observes a base sequence of AGCTAGCTAGCT.  Which of the following would be the complimentary strand?

• TGCATGCATGCA
• TCGATCGATCGA
• TAGCTAGCTAGC
• TTAAGGCCTTCC

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

• Replication
• Translation
• Transcription

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

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

What are the gaps between the newly synthesized DNA on the lagging strand called?

• Okazaki fragments
• Polymer gaps
• Helicase fragments
• Acidic gaps

The enzyme that unwinds the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase
