DNA Structure and Replication

This enzyme breaks Hydrogen bonds between the bases in DNA replication.

• Ligase
• Primase
• Helicase
• Polymerase

This base always pairs with Cytosine in a DNA strand.

• Guanine
• Adenine
• Thymine
• Uracil

This is the first step in DNA replication.

• DNA condenses
• DNA is synthesized
• DNA unzips
• DNA fragments are joined together

This is the sugar present in a DNA molecule.

• Ribose
• Glucose
• Deoxyribose
• Deoxyglucose

This is the shape of the DNA twisted ladder.

• Ladder
• Staircase
• Helicase
• Double Helix

This building block of DNA is made up of a sugar, a base, and a phosphate.

• Nucleus
• Nucleolus
• Nucleotide
• Lego

The bases of a DNA strand are held together by this bond shown by the X below.

• Carbon
• Nitrogen
• Hydrogen
• Oxygen
