DNA Replication Flashcards
1
Q
Describe the steps of DNA replication
A
- Enzyme DNA helicase breaks down the hydrogen bonds between bases and form 2 single strands so DNA strands can act as templates
- DNA nucleotides match up by complementary base pairing; adenine and thymine, cytosine and guanine
- DNA polymerase joins adjacent DNA nucleotides and forms a phosphodiester bond
- Each DNA molecule now has one original strand and one newly synthesised strand
