Question

Untranslated regions of the mRNA transcript may interact with motor proteins to enhance transport of the mRNA to a distinct region of the cell; or these regions may interact with proteins that repress the translation of the mRNA. True or False

Answer 1

The correct answer is "True".

Step-by-step explanation:

The levels of gene transcription are regulated in part by untranslated regions of the mRNA. These regions include: stem-loop structures, upstream initiation codons, internal ribosome entry sites, among others. The 3'-untranslated regions are the ones that could affect the transport and localization of the mRNA. These same regions may interact with proteins that repress the translation of the mRNA, particularly by binding to miRNAs.
