Question

Please do part B)
Consider the following segment of DNA, which is part of a much longer molecule constituting a chromosome:
5’-…ATTCGTACGATCGACTGACTGACAGTC…-3’
3’-…TAAGCATGCTAGCTGACTGACTGTCAG…-5’
If the DNA polymerase starts replicating this segment from the right,

PartA)
the molecule when the DNA polymerase is halfway along this segment.

5' GACTGACTGACAGTC 3'
..CTGACTGACTGTCAG 5'

PartB)
*Draw the two complete daughter molecules.
*Is your diagram in part A compatible with bidirectional replication from a single origin, the usual mode of replication?

Explanation / Answer

The two daughter molecules are 1st one 5’-…ATTCGTACGATCGACTGACTGACAGTC…-3’ (from original DNA) 3' -…TAAGCATGCTAGCTGACTGACTGTCAG…-5’ 2nd one 5’-…ATTCGTACGATCGACTGACTGACAGTC…-3’ 3’-…TAAGCATGCTAGCTGACTGACTGTCAG…-5’ (from original DNA) Not in diagram A because DNA polymerase is acting on one strand only. if there were two dna strands there can be bidirectional replication with a leading strand and lagging strand
