Before it leaves the nucleus, the mRNA is spliced to create mature mRNA. This splicing involves that cutting out of introns, leaving only the exons - which are the segments which code for a protein. Before it leaves the nucleus, the mRNA is spliced once again to create mature mRNA.
Answer:Radiometric dating allows us to indirectly date fossils up to billions of years old based on minerals in surrounding volcanic strata. The correct option is D.
Explanation:
Radiometric dating was first used by geologist after being published by Bertram Bollywood in 1907. During volcanic eruption, some minerals ( carbon) are trapped within the volcanic strata. These minerals are made up of radioactive isotopes which are unstable as they form decay products with a known constant rate of decay. This enables them to :
- access information about the absolute age of rocks,
- date a wide range of natural and man-made materials
- know even the age of earth. I hope this helps. Thanks
