How does the molecular clock work?A. It analyzes the brain functionality of two different species.B. It examines and compares th
e physical characteristics of two different species.C. It illustrates relationships between two different species.D. It compares the number of mutations that exist in the DNA of two different species.
Evolutionary biologists have been investigating the possibility that some evolutionary changes occur in a clock-like fashion. Over a long period of time, mutations may build up in any given stretch of DNA. The Molecular Clock is a way of interpreting random genetic mutations in every living creature and deduce from them it’s evolutionary past.
Molecular clock helps us tell time on an evolutionary scale. It measures the number of changes in a genome over time. These changes or mutations between two species accumulate over time. The molecular clock allows us to see both how individual species evolve as well as when species branch off from each other evolutionarily.
As ribosomes make their proteins, they may attach to the rough ER and insert the protein into the interior of the ER. The ER then begins folding the new proteins and transports them to areas in which chemical processing takes place
