Card preview (10)

#1
Front (Question)

What is the method of DNA replication known as and why

Back (Answer)

Semi conservative replication because half of the original DNA molecule is (conserved) kept in each of the two new DNA molecules

#2
Front (Question)

First step of DNA replication

Back (Answer)

• The originals DNA molecule is unwounded by the enzyme DNA helicase

#3
Front (Question)

Second step of DNA replication

Back (Answer)

• Hydrogen bond between the bases are broken by the unwinding and this forms two single polynucleotide DNA strands

#4
Front (Question)

Third step of DNA replication

Back (Answer)

• Each single polynucleotide acts as a template of the formation of a new strand

#5
Front (Question)

Forth step of DNA replication

Back (Answer)

• Free nucleotides are attracted to the exposed DNA bases by complimentary base pairing

#6
Front (Question)

Fifth step of DNA replication

Back (Answer)

• The new nucleotides are joined together by the enzyme DNA polymerase which catalyses condensation reactions to form two new paired strands

#7
Front (Question)

Sixth step

Back (Answer)

• The originals strand and the new strand joined together through hydrogen bonding

#8
Front (Question)

Two features of DNA structure which make DNA replication easier

Back (Answer)

Weak hydrogen bonds between bases which can be broken easily Double stranded can be used as template / Complimentary base pairing used for template of new strand

#9
Front (Question)

What direction does the DNA polymerase go from

Back (Answer)

5’ to 3’

#10
Front (Question)

Further information about leading and lagging

Back (Answer)

Look in book because diagram heavy explanation (Remember though DNA pairs have opposite 5’ and 3’ directions )
