Final answer:
The Kozak/AUG sequence on eukaryotic mRNA is recognized by ribosomes, which are crucial for the initiation of protein synthesis by ensuring translation begins at the correct AUG start codon.
Step-by-step explanation:
Recognition of the Kozak/AUG sequence is done by ribosomes, which are cellular structures where protein synthesis occurs. The Kozak sequence is a specific nucleotide sequence surrounding the AUG start codon on eukaryotic mRNA that helps to position the ribosome and start the translation process. It is important for the accurate initiation of translation because it helps the small ribosomal subunit to recognize and bind to the correct start codon on mRNA, ensuring that protein synthesis begins at the right location. This sequence is analogous to the Shine-Dalgarno sequence in prokaryotes, which serves a similar purpose in the initiation of protein synthesis.
In summary, the Kozak sequence assists ribosomes in identifying the start site for translation, and it ensures that proteins are synthesized correctly by starting at the proper AUG codon.
