Question
The following DNA sequence contains an origin of replication, which has been circled. Given this sequence, circle the primer below that can be used to synthesize a leading strand from this origin. 5'- UCUAAG -3' 5'- AGATTC -3' 5'- TCTAAG -3' 5'- AGAUUC -3' Write the first 5 bases that would be added to this primer by DNA polymerase as the leading strand grows in order of synthesis. Be sure to label its 5' and 3' ends. After a nuclease removes this primer, write the sequence that a DNA polymerase could use to fill in the gap. Be sure to label its 5' and 3' ends. Is replication of this sequence now completed? Explain why or why not.Explanation / Answer
Based on the given data,
a)
5’-AGATTC-3’
b)
GACGG
c)
5’AGATTC-3’
d)
Yes, in leading strand only primer sequence is enough to carry out entire stand synthesis. So, after nick sealing the DNA replication of this sequence is completed.
