$(5$ points$)$ Please match the following proteins$/$structures$/$RNA involved in translational initiation to their appropriate description.

$$

$$ PAB$1$

$$ eIF$4$G

$$ elF$4$E

Protein that binds the $3\text{'}$ Poly$($A$)$ Tail and plays a critical role in circularization of the mRNA for efficient translation by binding a protein at the cap

Adaptor protein that recruits the $40$ S subunit of the ribosome

Helicase that moves ahead of the ribosome to resolve secondary structure in the $5\text{'}$ UTR of the mRNA, and is dispensable for translation

Protein that directly binds the $5^{\text{'}}$ methyl guanosine cap

Protein that is bound to a guanine nucleotide and is involved in the joining of the $60$ S subunit at the start codon
