DNA Fragment – an overview | ScienceDirect Topics
DNA fragments generated by sonication in Step 1 will be end polished to produce a library of DNA fragments with blunt, 5′-phosphorylated ends that are ready for ligation. The end polishing is accomplished by using the T4 DNA polymerase, which can fill in 5′ overhangs via its polymerase activity and recess 3′ overhangs via its 3′→5′ exonuclease activity. The phosphorylation of 5 …

Searching for DNA – CliffsNotes
Searching for DNA Searching for DNA The ability to retrieve DNA from ancient materials and museum specimens has given archaeologists and anthropologists hope of a glimpse at ancient life. Biochemists have successfully obtained DNA from extinct animals and plants. Evolutionary biologists have used the DNA to draw lineage patterns from the data.

DNA Size Selection: Basics & Development – NVIGEN
When fragments are short, the read is limited. So it’s desired to remove smaller fragments using size selection, which allows the sequencers to focus on the DNA fragments most amenable to producing the longest reads. How does DNA size selection work? Figure 1. DNA size selection workflow. Mix: Mix MagVigen™ nanoparticles with DNA/RNA sample.

PieceMaker: selection of DNA fragments for selector-guided multiplex …
A DNA sample is specifically fragmented by restriction digestion, and fragments containing sequences of interest are circularized by hybridization to the target-specific selector ends and ligation to the general segment. The general sequence is thus incorporated into the DNA circles, which can then be amplified in multiplex by PCR using a standard primer pair. By use of a structure-specific endonucleolytic cleavage reaction prior to ligation, the 5′ ends of restriction fragments …

DNA fragmentation – Wikipedia
DNA fragmentation is the separation or breaking of DNA strands into pieces. It can be done intentionally by laboratory personnel or by cells, or can occur spontaneously. Spontaneous or accidental DNA fragmentation is fragmentation that gradually accumulates in a cell. It can be measured by e.g. the Comet assay or by the TUNEL assay. Men with sperm motility defects often have high levels of sperm DNA fragmentation. The degree of DNA fragmentation in sperm cells can predict outcomes …

How do you separate the desired DNA from all others?
All possible DNA purification chemistries can be broken down into five basic steps: 1) disrupting the cellular structure to produce a lysate, 2) separating the soluble DNA from other insoluble material, including cell debris, and 3) binding the DNA of interest to a purification matrix.

Correct option is B) DNA probes are short DNA sequences that are used to identify the desired gene, out of a large number of DNA fragments, carrying the complementary nucleotide sequence. PCR – technique amplify the DNA samples.
