	Ribonucleic Acid Part One Article
		He knew that ribonucleic acid is important in the initiation of DNA synthesis, acting in a coenzyme-like fashion.
		He reasoned that if nucleic acids were provided to the cell in high amounts, they could be utilized in metabolism without destroying the nucleus or cytoplasm, and thereby enable the cells to live longer at a higher energy level.
		Alternatively, he theorized that the life-prolonging effect of yeast nucleic acid might be due to its ability to stimulate the immune system, since sodium yeast nucleinate was known to stimulate the growth and proliferation of white blood cells (leukocytes).

	RNA (Ribonucleic Acid) Information on Healthline
		Its purpose is to transfer a specific amino acid from the cytoplasm and incorporate it into the growing polypeptide chain on the polysome.
		The aminoacyl-tRNA (the tRNA carrying the amino acid) binds to the large subunit of a ribosome, where antiparallel basepairing occurs between the anti-codon of the tRNA and the complementary codon of the associated mRNA.
		During translation, the deacylated tRNA (i.e., with its amino acid removed) is released from the ribosome and becomes available once again for recharging with its amino acid.

	rna: ribonucleic acid
		Each code word is called a codon, a sequence of three adjacent nucleotides that specifies one of twentry amino acids.
		It can either specify the amino acid methionine in the middle of a protein, or it can act as an initiation or start signal, which tells the ribosome, "Start translating here." All proteins proteins start out with methionine as their first amino acid, but it is enzymatically removed from some proteins after synthesis.
		It carries amino acids and places them in a protein that is being produced according to the instructions of mRNA.

	NDI Terminology - ribonucleic acid (Site not responding. Last check: 2007-11-05)
		RNA; the nucleic acid in which the sugar is ribose, constituting the genetic material in the RNA viruses and playing a role in the flow of genetic information.
		Ribosyl moieties are linked via phosphate groups attached to their 5' and 3' hydroxyl groups to form the backbone of a linear polymer, with purine and pyrimidine bases attached to the sugars as side chains.
		Many RNA molecules contain bases modified by posttranscriptional processing (methylation, deamination, isomerization), and some contain secondary structure such as base pairing between self-complementary sequences, which stabilizes specific conformations.
