Question

3. Shown below is a double stranded DNA. Replicate this DNA fragment and show the products formed from this replication. Remember, in replication, each strand is copied into a new daughter strand. In your answer, indicate which strands are the new daughter strands (mark with D) and which strands are the already existing parent strands (mark with P as shown below). Label the 5’ and 3’ ends of all DNA. HINT: You should have 2 double-stranded DNA fragments after replication.

P: 5’ GAATCAGATACAT 3’

P: 3’ CTTAGTCTATGTA 5’

Answer 1

REPLICATION RULE:

When the parent strand replicate into daughter strand it forms the complementary base pairs that is A base pair with T and G base pair with T. Each parent strand give rise to a double-stranded daughter strand

first parent strand P: 5’ GAATCAGATACAT 3’

its daughter stand D: 5’ GAATCAGATACAT 3’

3' CTTAGTCTATGTA 5'

SECOND parent strand P: 3’ CTTAGTCTATGTA 5’

its daughter stand D: 3’ CTTAGTCTATGTA 5’

5'GAATCAGATACAT 3’
