RFLP analysis of genomic DNA is facilitated by Southern blot analysis. After electro-phoresis, DNA fragments in the gel are denatured by soaking in an alkali solution. This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix). A replica of the electrophoretic pattern of DNA fragments in the gel is made by transferring (blotting) them to a sheet of nitrocellulose or nylon membrane. This is done by placing the membrane on the gel after electro-phoresis and transferring DNA fragments to the membrane by capillary action or electro-transfer. DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.
I believe that the answer is D. If something has evolved, it can not interbreed with its old species. I think this is right! Rate Brainliest user please!
Answer: Natural selection is a process by which species of animals and plants that are best adapted to their environment survive and reproduce, while those that are less well adapted die out.
bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic
