number the steps below In order

A. hydrogen bonds between nucleotides form

B. hydrogen bonds between nucleotides break

C. Strands of Dna separate

D.free nucleotides are attracted to exposed bases on the loose strands of dna

• B,C,D,A

• A,B,C,D

• C,B,A,D

primase does what

• adds RNA primers that re needed bc DNA polymerase 3 can only add new nucleotides to an existing strand

• it adds new nucleotides to build new DNA strands

• it removes RNA primers and replaces them with DNA nucleotides

• attaches okazaki fragments together

dna polymerase 3 does what

• adds RNA primers that re needed bc DNA polymerase 3 can only add new nucleotides to an existing strand

• it adds new nucleotides to build new DNA strands

• ti removes RNA primers and replaces them with DNA nucleotides

• attaches okazaki fragments together

what does DNA polymerase 1 do

• adds RNA primers that re needed bc DNA polymerase 3 can only add new nucleotides to an existing strand

• it adds new nucleotides to build new DNA strands

• it removes RNA primers and replaces them with DNA nucleotides

• it attaches okazaki fragments

what does ligase do

• adds RNA primers that re needed bc DNA polymerase 3 can only add new nucleotides to an existing strand

• it adds the new nucleotides to build new DNA strands

• it removes RNA primers and replaces them with DNA nucleotides

• attaches okazaki fragments together

what keeps the strands once separated by helicase from coming back together

• primase

• primer

• single strand binding proteins

what starts as a starter sequence for DNA polymerase 3

• rna primer

• dna polymerase 1

• hilcase

• primase
