GO:0002191:   cap-dependent translational initiation
The process where the Cap structure (composed of a 7- methylguanosine (m7G) group and associated cap-binding proteins) located at the 5" end of an mRNA molecule, which serves as a molecular tag that marks the spot where the 40S ribosomal subunit is recruited and will then scan in a 5" to 3" direction until an AUG codon is encountered in an appropriate sequence context to initiate mRNA translation.
