During translation in eukaryotes, how is the 3' end of the mRNA involved? It stops translation if there is no stop codon in the mRNA It assists in the formation of the initiation complex involving the ribosome large subunit, mRNA and stating amino-acyl tRNA It prevents the formation of the initiation complex by increasing the hydrolysis of the amino acid from the initial amino acyl tRNA It forms a circular RNA molecule by being ligated to the 5' end of the mRNA It stops translation if there is no stop codon in the mRNA

In eukaryotes, the 3' end of the mRNA is important in the initiation of translation because it contains Kozak sequences that aid in initiation of translation in the 5' to 3' direction. The 3' poly(A) tail and PABP bind initiation factor eIF4G, stabilizing the 5' end of the mRNA. eIF4A is attached to the 3' end and removes any secondary structure that might prevent translation. Translation occurs in the 5' to 3' direction.
Consider protein made up of 150 amino acid residues. How many GTP molecules will be required for elongation? GTPs are consumed per peptide bond formed (one elongation step and one termination step). 150 total for initiation and elongation, and 149 total for termination. Can you calculate? Which of the following statements are incorrect? Translation in eukaryotes uses only mRNA, which introns have been spliced out. With few exceptions, both eukaryotes and prokaryotes use the same genetic code in most genes. Initiation and termination are found and generally speaking, RNA splicing occurs in both prokaryotes and eukaryotes. Protein synthesis occurs by nucleophilic attack by the amino group of the A-site aminoacyl-tRNA on the carbonyl of the growing peptide chain. None of the above. Which of the following mRNA sequences can be translated using the CUG start codon? Immune system proteins displayed on the major histocompatibility complex (MHC). Proteins involved in transcription factors. Antibodies. Enzymes.
