DNA replication

Question 1

what is the definition of semi conservative replication:

Answer 1

• each dna strand acts as a template
• the daughter dna has one new dna strand and one original parental strand

Question 2

process:

Answer 2

• dna helicase breaks the hydrogen bonds between the complementary base PAIRS BETWEEN the two strands of the double helix causing the double helix to unwind
• each of the separated parental dna STRANDS will act as a template
• free floating nucleotides within the nucleus are attracted to the complementary base PAIRS on the parental dna strandS acting as a template
• the adjacent nucleotides are joined together by a phosphodiester bond via a condensation reaction that is catalysed by dna polymerase
• there is now TWO SETS of daughter dna. one strand being the original parental dna and the other being the newly synthesised dna
