When genomic DNA is fragmented and cloned, the screening of the desired gene is done by using

Hi,

It depends upon the size of DNA fragment or the length of the nucleotide obtained. However there are some basic methods through which the gene of intrest can be screened out:

i) Nucleic acid hybridizations
ii) Antibody probes
iii) Polymerase Chain Reaction(PCR)
iv) Restriction Fragment analysis
v) DNA sequencing
