When does replication occur?

• G0 phase
• G1 phase
• G2 phase
• S phase

Name this structure

• double helix
• nucelotide
• twisted ladder
• hydrogen bond

Describes the twisted ladder-like shape of a DNA molecule

• Nitrogen Base
• Hexagon
• Double Helix

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

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

• Replication
• Translation
• Transcription

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

Replicate the following strand of DNA: 
AATCATGGA

• AATCATGGA
• TTAGTACCT
• UUAGUACCU
• GGATAUCUA

The picture below shows the steps of DNA replication beginning with step one and ending with step three.

​Because you are reusing the old, or parent, DNA strand DNA replication is said to be

• Semi- Conservative

• Semi-discontinuous

• Continuous

• Fully-Conserveative
