What role does rna stability play in gene regulation? list three types of rna structural elements that can affect the stability of an rna molecule in eukaryotic cells. explain how these elements act to influence rna stability.

RNA structural elements include double stranded regions of RNA formed by RNA folding upon itself to form a hairpin loop for example. These structures provide structural stability to RNA and allows for RNA to function as enzymes in some instances.

Another RNA structural element is the polyA tail formed at the end of mRNA sequence after mRNA maturation to prevent degradation of mature mRNA by RNase.

Another RNA structural element is the 5'cap formed at the 5' of mRNA sequence after mRNA maturation to prevent degradation of mature mRNA by RNase and also acts as a signalling target for transport of mRNA.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
