Once elongation is underway, tRNAs involved in the process occupy a series of sites on the complexed ribosome. The occupation of sites occurs in the following order.
A) A Site, P Site, E Site, S Site
B) P Site, E Site, A Site
C) A Site, S Site, E Site
D) A Site, P Site, E Site

D) A Site, P Site, E Site

Explanation:

The first step in the elongation process is the position of the second tRNA in the A site (because the first tRNA is the start codon that is in the P site during the initiation of translation) then an amino acid that is in the P site is transferred to the amino acid that is in the A site, after this the translocation happens, where the RNAm moves in 5' direction moving the tRNA that was in the A site to the P site and the tRNA that was in the P site to the E site, in the E site the tRNA is released.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
