DNA Replication (8.3)

A DNA nucleotide contains all of the following, except...

• Deoxyribose
• Phosphate group
• Nitrogenous base
• Cholesterol

What is the shape of DNA?

• Double helix
• Triple helix
• Flat, bilayer
• Three-pronged rigid ladder

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

• Replication
• Translation
• Transcription

DNA replication turns one strand of DNA into two new strands of DNA. What percent of each new strand is the old strand?

• Half of each new DNA is the old DNA
• The old strand of DNA was digested, so none
• The new DNA is entirely made up of the old DNA
• About every sixth base comes from the old DNA

Sometimes, DNA is called "semi-conservative." Why might this be?

• The old strand is "conserved" and used to make the new strands
• Uracil is "conserved" in that it is only used to make the new strands
• ATP is "conserved" via the usage of facilitated diffusion
• Ligase is "conserved" in that it is denatured by the process

What will the first four bases of the new DNA strand look like if copying the template strand?

• TGGT
• ACCA
• GTTG
• CAAC

Why does DNA replicate?

• To create another copy for the new cell
• To create a duplicate copy in case the original gets damaged
• To create a new copy to replace the damaged original

DNA replication results in

• 2 completely new DNA molecules

• 2 DNA molecules that each contain a strand of the original

• 1 new DNA molecule and 1 old

• 1 new molecule of DNA

The new DNA strand formed after DNA replication is an exact copy of the original strand

• True

• False
