Which Best Describes Okazaki Fragments in Dna Replication
DNA pol I adds the nucleotides to the 3 end of fragment B When it encounters the 5 end of fragment A DNA pol I falls off leaving a gap in the sugar-phosphate backbone between fragments A and B. Try to visualize.

Mutations result either from errors in DNA replication or from the damaging effects of mutagens such as chemicals and.
. A DNA replication would occur but the leading strand would be composed of many small fragments. C DNA replication would occur but the lagging strand would be composed of many small fragments. A mutation Section 141 is a change in the nucleotide sequence of a short region of a genome Figure 141AMany mutations are point mutations that replace one nucleotide with another.
DNA ligase closes the gap between fragments A and B. B DNA replication would not occur normally because DNA would not unwind and single-stranded template would not be exposed. These steps will be repeated as the replication fork opens up.
Others involve insertion or deletion of one or a few nucleotides. DNA transcription is a similar process except only a part of the DNA sequence is copied to form a messenger RNA Chapter 5 6 DNA DNA Replication History DNA Comprised of genes In non-dividing cell nucleus as chromatin ProteinDNA complex Chromosomes form during cell division Duplicate to yield a full set in daughter cell DNA is Genetic Material From Chapter 2 Nucleic.
