The transfer of information from DNA to RNA to protein is called Central Dogma. The formation of protein from mRNA is translation. The translation begins with initiator codon AUG in mRNA. The ribosome small subunit (30s) binds to the RNA. The tRNA binds and then large subunit (50s) attaches with mRNA.
Thus, reading from 5’ to 3’, this RNA product has the sequence <u>AUG.</u> It binds to the small subunit of the <u>ribosome.</u> It is joined by the large subunit, completing the <u>initiation</u> stage of the process of <u>translation</u>.
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
