NGSS.HS-LS3-1

Building blocks of nucleic acid- Made of deoxyribose sugar, phosphate group, and a nitrogenous base

• Chromosomes

• Genes

• Nucleotides

• DNA

Bind to the single strands of the open DNA molecule to keep the strands apart

• Helicase

• Ligase

• Polymerase

• Single Stranded Binding Proteins (SSBP)

Adds in the complementary nitrogen bases on the leading and lagging strand

• Helicase

• Ligase

• Polymerase

• Single Stranded Binding Proteins (SSBP)

The fragments of DNA created on the lagging strand because DNA polymerase is moving backwards

• Helicase

• Ligase

• Polymerase

• Okazaki Fragments

Glues the okazaki fragments together

• Helicase

• Ligase

• Polymerase

• Single Stranded Binding Proteins (SSBP)

Unzips the DNA by breaking the hydrogen bonds

• Helicase

• Ligase

• Polymerase

• Okazaki Fragments
