What is the function of transfer RNA (tRNA)?
To act as an adaptor molecule in protein synthesis.
What is the significance of the 'wobble' position in a codon?
It allows flexibility and efficiency in the use of tRNA.
What is the role of ribosomes in protein synthesis?
To serve as the factories for protein synthesis.
Test your knowledge on ribosomes and their structure, including the A, P, and E sites, as well as the role of protein and rRNA complexes in translation.
