protein Flashcards
Why is DNA described as an antiparallel molecule?
The two strands run in opposite directions
What might be the consequence of a mutation in the DNA polymerase enzyme?
Decreased accuracy of DNA replication.
How do cells ensure that both daughter cells receive an identical copy of DNA?
By utilizing semi-conservative replication.
What is the function of ligase in DNA replication?
To bond Okazaki fragments together.
How does the leading strand differ from the lagging strand during DNA replication?
The leading strand is synthesized continuously, while the lagging strand is synthesized in fragments.
What would happen if helicase did not function properly?
DNA strands would not separate, preventing replication.
How do environmental factors influence DNA replication?
They can cause mutations.
What is the significance of the 5’ and 3’ ends of a DNA strand?
They indicate the direction of replication.
During which phase of the cell cycle does DNA replication occur?
S phase.
Which nucleotides pair together during DNA replication?
A with T and C with G.
