In which population would the rate of genetic drift be the greatest?

A genetic drift is defines as the change in the allele frequency of an existing population. It arises as a result of random variation in a population. The rate of genetic drift would be greatest in a small population that are geographically isolated from the parent population. A change in the allele frequency of  a population as a result of chance rather than the natural selection.

The mRNA transcript that is produced in the nucleus is in immature form, it had to get matured, and then its capping and tailing is done. 5' cap is added and a poly A tail is added at 3' end of this mRNA. This helps it to get matured. moreover for its maturation the non-coding regions (introns) are removed and exons are packed up again to form a mature mRNA.

This mature mRNA then proceeds to its way to the ribosomes for translation of proteins.
