Final answer:
The terms 'docking site' and 'selector sequence' refer to components of the translation process; the docking site binds tRNAs to the ribosome, and the selector sequence identifies the start codon for translation initiation. The correct answer to the multiple-choice question is (C).
Step-by-step explanation:
In the context of molecular biology and gene expression, the terms docking site and selector sequence refer to specific aspects of the translation process. The docking site is typically associated with the ribosome, where translation occurs, including areas such as the A (aminoacyl) site, P (peptidyl) site, and E (exit) site where tRNAs bind and interact during protein synthesis. The selector sequence, on the other hand, helps the ribosome identify the start codon of the mRNA, which is usually AUG, signaling the beginning of translation.
When answering the multiple-choice question, the correct choice is (C) Docking site: Binds ribosomes; Selector sequence: Identifies start codon. This is because it accurately describes the role of the docking site in the binding of ribosomes during translation and the selector sequence in identifying the correct place to initiate this process.
