in DNA probe, short single stranded dna labelled with radioactive is mixed with the double stranded dna fragment that contains gene of interest. dna probe is usrd to locate gene of interest in the dna. the question is how do scientist know the base sequence of the radioactively labelled dna before it is mixed with the double-stranded dna fragments that contain the gene?
i hope u can understand the ques. it's a bit hard for me to explain this thing...thanks in advanced.

The probe is just the complimentary sequence of the gene, so that it will bind specifically to your gene of interest. This is only done when the sequence of the gene (or at least part of it) is already known.

Hm, they the two are straight forward how you are able to examine the guy´s DNA and p.c. out it to that specific guy or woman. And the differencies... i think of that DNA fingerprint form of shows the guy´s common DNA, and DNA sequencing analyses the DNA into its aspects after which shows those separate aspects and how they extra healthful at the same time and make up the full DNA. nicely, i'm not an expert in this, i'm hoping my answer delivers some theory of those issues and isn´t a manner from the suited element.
