Question

When many genes are transcribed into a single mRNA strand, the mRNA is said to be __.

Answer 1

mRNA can either be monocistronic or polycistronic. The former is the type in which a particular gene codes for a single mRNA strand, while the latter is the type in which many genes are transcribed into a single mRNA strand. Eukaryotes have monocistronic mRNA while prokaryotes have polycistronic mRNA.
