Mendel cross breed pea plants with different colors of seed plants and different seed shapes to see is that would affect the shape.
DNA a double-helix like structure, containing multiple nucleotide sequences consisting of a phosphate group, a sugar group, a nitrogenous base, and a hydrogen bond between two nucleotides. The hydrogen bond is weak so the double-helix can "unzip" and make RNA. I hope this helps!
because you know, i mean you know.
Some isotopes are stable, but others are radioactive. An isotope will be radioactive if its nuclei are unstable. Large atomic nuclei, with more than 93 protons and their associated complement of neutrons, are inherently unstable. Uranium and plutonium are examples of such elements.
