Answer:
C. a sequence complementary to the promoter of the operon
Explanation:
MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are two major classes of small non-coding RNAs (sncRNAs) that function to control gene expression by binding to complementary RNA transcripts. Antisense oligonucleotides exploit this natural ability of the sncRNAs to regulate target gene expression.
An operon is a procaryotic single-strand DNA that contains a group of genes modulated by one single promoter, which are transcribed together to produce a single polycistronic messenger RNA (mRNA). In this example, the antisense complementary oligonucleotide will bind to the mRNA to modulate its transcription and, consequently, also protein synthesis.
If you’re a big fan of quinoa, or chia seeds, you may have heard them touted as complete proteins. In a nutshell, that means they contain all of the nine essential amino acids required to build and repair protein tissues in the body. But the question is: does that matter?
The short answer is no, not really. But first, let's back up a step.
Animal-based foods like eggs, dairy, fish, and meat are complete proteins; while most plant foods are incomplete—meaning certain amino acids are missing from the protein puzzle.
Some people believe that in order to utilize plant protein efficiently, you must eat so-called "complementary proteins" together. Rice and beans are a good example of complementary proteins, because the amino acids that are missing from beans are found in rice and vice versa.
