DNA Replication

Which sequence of DNA bases would pair with this partial strand
CAT TCA CTG

• ATG TGA CAG
• TAC ACT GTC
• GTA AGT GAC
• CAT TCA CTG

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids
• nucleotides
• fatty acids
• polysaccharides

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

Which enzyme is responsible for adding nucleotides?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

The process of DNA replication is called semi conservative because it results in

• none of these
• Two DNA molecules.  One original molecule and one with two new strands
• two exact copies with new strands
• two identical molecules, each with 1 original strand and one new.

Looking at DNA template it is read by DNA polymerase in what direction (NOT THE NEW STRAND)

• 3'-5'

• 5'-3'

• DNA is not directional

New DNA that is being laid down is being created in the

• 3'-5'

• 5'-3'

• DNA is not directional

Polymerase is attached to a free

• 3' end

• 5' end

• nucleotide

• sugar (deoxyribose)

one nucleotide's sugar is held to another nucleotide's phosphate group

• hydrogen bond

• phosphodiester bond

• nucleotide

• covalent bond
