NGSS.HS-LS3-2

The enzyme that unwinds the DNA to prepare for replication

• helicase

• replicase

• polymerase

• synthase

Which of the following identify why DNA replication is referred to as 'semi-conservative'?

• 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

Put the pictures in order, according to the process of DNA replication.

• 3, 4, 2, 1

• 3, 1, 4, 2

• 2, 1, 4, 3

• 3, 4, 1, 2

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?

• Helicase

• DNA Polymerase

• Ligase

• Lactase

Which of the following has the correct steps of DNA replication in order?

• Helicase unzips DNA; Primer & new nucleotides added; Ligase attaches fragments

• Ligase unzips DNA; Helicase adds new nucleotides; Ligase separates new & old fragments

• Helicase opens DNA at origin; Ligase attaches new nucleotides; Covalent bonds form between nucleotides

• Covalent bonds broken by helicase; DNA polymerase builds new DNA strand; Ligase connects fragments
