James Watson and Francis Crick are credited with deducing the structure of DNA. This was possible due to an x-ray photograph of DNA taken by Rosalind Franklin.
Franklin
Rosalind Franklin took the x-ray photograph which allowed Watson and Crick to deduce the structure of DNA itself.
Initially you inject it into the wells.
The probe is the second strand of DNA that forms double-stranded DNA with the target gene.
neucleus is the site of DNA replication hence it forms DNA
The DNA molecule forms a double helix. The linear DNA chromosomes of eukaryotes form a highly supercoiled double helix.
