The step in translation initiation that is unique to the eukaryotes is:
<span>formation of the preinitiation complex ribosome assembly
</span>
Here are the processes involved in the Translation Initiation of Eukaryotes
1) 5'cap is used to position the mRNA on the 40S ribosomal subunit
2) ribosome scans down the mRNA looking for an AUG.
3) There is an initiator methionine-tRNA
4) The initiating AUG codon is often within a consensus sequence called the Kozak sequence (5'-ACCAUGG-3')
5) After binding the cap, ribosomes scan down the mRNA until the Kozak sequence is reached and translation begins
<span>6)The poly (A) tail and 5'-cap binding proteins help the initiation complex form

The answer to this question is c
Transcription is the correct answer
Answer:
c) receptor; control center; effector.
Explanation:
Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.
For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.
