Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.

a) ribosomes on the rough endoplasmic reticulum
mRNA (created by DNA) leaves the nucleus through the nucleic pores, and from there will enter a nearby ribosome since the rough endoplasmic reticulum is surrounding the nucleus. It is there that polypeptides are made and transported in vesicles to the Golgi apparatus because they cannot touch the cytoplasm when still incomplete. Hope this helped.
After the orginal trand has been seperated in DNA replication, the tRNA's bring together an amino acid, strands wind tightly together -corresponding base pairs are laid, and lastly, the bases are proofread for any errors.
