RNA Regulation and Antisense RNA
Antisense RNAs are single-stranded RNA molecules that can bind and inhibit specific mRNA translation to protein.

Attenuation
Attenuation is a mechanism utilized by bacteria to regulate unnecessary gene expression.

Small Regulatory RNAs
Small regulatory RNAs are non-coding RNA molecules that play a role in cellular processes such as activation or inhibition processes.
