The answer is mRNA (messenger-RNA). In most eukaryotes, transcription occurs by firstly creating a primary
transcript. This primary transcript is
processed into a pre-mRNA that later becomes a mRNA
by removing introns. Processing of the RNA also includes
polyadenylation and 5’ capping.
The answer should be the refractory period

Answer:
The correct answer is d. eukaryotes almost always produce polycistronic mRNA
Explanation:
In eukaryotes one transcription unit contains the information of only one gene which codes for only one protein or polypeptide therefore eukaryotic mRNA is called monocistronic mRNA.
In prokaryotes transription unit contains set of genes adjacent to each other which are transcribed together and codes for multiple proteins. So prokaryotic mRNA is called polycistronic mRNA.
Almost all messenger RNA present in eukaryotes are monocistronic mRNA because eukaryotes are more complex than prokaryotes and require modification at many stages which is easily possible with monocistronic mRNA.
