Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
<span>G1 stage is the first of four periods of the cell cycle that occur in eukaryotic cell division. In this piece of interphase, the cell orchestrates mRNA and proteins in readiness for resulting steps prompting mitosis. G1 stage closes when the cell moves into the S period of interphase.</span>
