Three examples would be gamma rays (usually these rays are emitted from unstable isotopes and can be used in nuclear experiments and testing) ultraviolent rays that are emitted from the sun and can cause sunburn and even skin cancer because the rays mutate the DNA in the skin cells nucleus. And also X-Rays, microwaves, and radio waves, which is usually harmless because it isn’t enough radiation to mutate DNA in our cells
I hope this is what you wanted
Thymine has a methyl group and is better suited for the storage property of the DNA molecule as it is far more stable compared to Uracil.
RNA contain Uracil instead of thymine so as to make differentiation of RNA molecule from DNA molecules easier.
The answer is Lionfish
are native to the tropical Pacific. There are no natural water routes of warm
water between the Pacific and Atlantic oceans.
Invasive species is a species that colonizes an environment
in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally
found in the indo-pacific, which is their
native environment. However, their presence
in the eastern United States has have threatened
the ecosystem of the region. The fish has decimated fisheries and reef
ecosystem since they also don’t have natural predators in the region. Therefore,
their population explodes unchecked.
The biggest difference between prokaryotic and eukaryotic is that eukaryotic cells have a nucleus and prokaryotic cells do not.
