A chromatogram showing the DNA sequence of the sense strand corresponding to a specific gene would contain both exons and introns. The separation of homologous chromosomes during meiosis is defined by: If a man freezes his sperm and becomes a woman with women parts, can they impregnate themselves with their own sperm?
How great of a botanist could George Washington Carver have been if he was a creationist? Is telling the truth about genetics and I. The oldest crystals on Earth that were formed on Earth are zircon crystals, and are approximately 4. Asteroids in the solar system have been clocked at 4. We assume that the Earth is probably as old as the asteroids, because we believe the solar system to have formed from a collapsing nebula, and that the Earth, being geologically active, has simply destroyed any older zircon crystals that would be its true age, but we can't really be certain.
The building blocks that the Earth is made of, the asteroids are 4. Based on astronomical models of how stars work, we also believe the Sun to be about 4. Radiometric dating is a widely accepted technique that measures the rate of decay of naturally occurring elements that have been incorporated into rocks and fossils.
Every element is defined by the particular number of protons, neutrons, and electrons that make up it's atoms. Sometimes, the number of neutrons within the atom is off. These atoms, with an odd number of neutrons, are called isotopes. Because they do not have the ideal number of neutrons, the isotopes are unstable and over time they will convert into more stable atoms.
Evolution: Library: Radiometric Dating
Scientists can measure the ratio of the parent isotopes compared to the converted isotopes. The rate of isotope decay is very consistent, and is not effected by environmental changes like heat, temperature, and pressure. This makes radiometric dating quite reliable. However, there are some factors that must be accounted for.

For example, sometimes it is possible for a small amount of new "parent" isotopes to be incorporated into the object, skewing the ratio. This is understood and can be corrected for. Carbon is the most commonly used isotope for dating organic material plants, animals. Plants and animals continually take in carbon during their lifespan. When they die, they no longer acquire carbon and so we can measure the decay of the isotope to determine when the plant or animal died.

Because carbon decays relatively rapidly compared to other isotopes, it can only be used to date things that are less than 60, years old. Anything older would have so little carbon left that you couldn't accurately measure it. However, the rapid decay allows precise dating - accuracy within just a couple decades.
When dating older objects, namely rocks, it is necessary to use other isotopes that take a much longer time to decay. The most common isotopes used are uranium and uranium there are multiple isotopes of uranium. The uranium isotopes eventually convert into lead isotopes.
