An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
Answer:
The correct answer is option c. "multimale/multifemale".
Explanation:
One of the most common primate groups that could be found in nature are multimale/multifemale groups. This kind of primate grouping is seen more often when predation pressure is high.
