RNA stands for ribonucleic acid. It's primary function is to make ribosomes, hence the answer is 'a'
Sea lions are noisier, seals are generally quieter, seals lack external ears, while sea lions have small flaps for ears.
The information stored in the order of bases is organized into genes: each gene contains information for making a functional product. The genetic information is first copied to another nucleic acid polymer, RNA (ribonucleic acid), preserving the order of the nucleotide bases. Genes that contain instructions for making proteins are converted to messenger RNA (mRNA). Some specialized genes contain instructions for making functional RNA molecules that don’t make proteins. These RNA molecules function by affecting cellular processes directly; for example some of these RNA molecules regulate the expression of mRNA. Other genes produce RNA molecules that are required for protein synthesis, transfer RNA (tRNA), and ribosomal RNA (rRNA).
As of now Sudbury has some of the cleanest air in all of Ontario. That’s hard to believe given the city once emitted 2.5 million tonnes of sulfur dioxide per year due to the Lumber industry. In the 1980s, the “Sudbury” became known as a unit of pollution, against which other industrial cities were measured. It’s now become known as a unit of restoration.
