In Eukaryotes,the 3ʹ End of the MRNA Is Important in the Initiation

Multiple Choice

In eukaryotes,the 3ʹ end of the mRNA is important in the initiation of translation because

A) it contains Kozak sequences that aid in initiation.
B) translation occurs in the 3ʹ to 5ʹ direction.
C) eIF4A is attached to the 3ʹ end and removes any secondary structure that might prevent translation.
D) the 3ʹ poly(A) tail and PABP bind initiation factor eIF4G,stabilizing the 5ʹ end of the mRNA.
E) it contains Kozak sequences that aid in initiation of translation in the 3ʹ to 5ʹ direction.
