Which sections in mature rna do not code for amino acids?

The 5' cap and ploy A tail at 3' end

Explanation:

A newly transcribed RNA in eukaryotic is termed as pre-mRNA. After the processing it becomes a fully mature mRNA.

During the processing capping and splicing is done as follows-

Thus, during processing, both the ends or pre-mRNA are modified by the addition of some chemicals. These additional chemical sections that are added to the 3' and 5' ends do not code for any amino acid.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
