FAQ
Reader questions
How does semi-conservative replication ensure genome stability?
Each parental strand serves as a template, so errors are minimized and mismatched segments can be corrected by dedicated repair pathways.
What role do DNA polymerases play in replication fidelity?
Polymerases select correct nucleotides and provide proofreading functions that remove mismatched bases before duplication proceeds.
Why are polymerase processivity and speed important in cell division?
Higher processivity allows continuous synthesis on leading strands, while controlled speed reduces collision risks with transcription machinery.
How do click chemistry tools enhance replication research?
Click reactions enable precise labeling of newly synthesized strands, making it easier to track synthesis events and repair patterns.
