The function of Initiation factor 3 (IF-3) is:Group of answer choices1. To stabilize the 30S subunit and enable it to bind to mRNA at recognition site.2. To check for the accuracy of the first charged tRNA.3. To recognize the Shine/Dalgarno sequence by complementary base pairing.4. To bind the charged initiator tRNA and deliver it to the A site of the 3OS ribosome.5. To prevent charged tRNA from entering the A site of the 30S
