1. During the initiation of translation, what are the first twocomponents to come together?
a. the small and large ribosomal subunits
b. the small ribosomal subunit and the tRNA
c. the small ribosomal subunit and the mRNA
d. the large ribosomal subunit and the mRNA
e. the mRNA and the tRNA
Answer:
C. Small ribosomal subunit and the mRNA.
Explanation- Initiation of translation occurs by binding of IFs(Initiation Factors such as IF1, IF2 & IF3 in prokaryotes) tothe smaller subunit of ribosome. IF3 prevents the premature bindingof the larger subunit.Then the mRNA binds to the 16s rRNA presentin smaller subunit of ribosome.
