DNA Replication

• What are the two strands used for in DNA replication?

  They serve as templates for new strands

  
• What is the composition of new DNA after replication?

  One original strand and one new complementary strand

  
• What enzyme binds to DNA during replication?

  DNA helicase

  
• What does DNA helicase do during replication?

  It breaks hydrogen bonds between DNA strands

  
• What happens to the DNA helix during replication?

  It unwinds and separates into two strands

  
• What do free-floating nucleotides do during DNA replication?

  They form hydrogen bonds with complementary bases

  
• How are complementary strands produced during replication?

  Each strand is used as a template
• What role does DNA polymerase play in DNA replication?

  It forms phosphodiester bonds between nucleotides

  
• How many new DNA strands are synthesized during replication?

  Two new DNA strands
• What is the significance of the hydroxyl group in DNA strands?

  It forms bonds between adjacent nucleotides
• What type of linkage is formed between nucleotides in DNA?

  Phosphodiester linkage
• In what direction do the two strands of DNA run?

  They run in opposite directions
• What does the 5 carbon end of one strand face in relation to its matching strand?

  It faces the 3 carbon end of the matching strand
• What reaction does DNA polymerase catalyze?

  Condensation reaction between nucleotides

  
• What does DNA polymerase form between adjacent molecules?

  Phosphodiester bonds
• What is the process of DNA replication called?

  Semi-conservative replication

  
• What is the role of complementary base pairing in DNA replication?

  It ensures accurate synthesis of new strands
