The Two Nucleic Acids It is not very fruitful to discuss whether proteins or nucleic acids are more important.
The nucleic acids are DNA and RNA (ribonucleic acid), which function together to manufacture the cell’s proteins.
The advantage of high-resolution autoradiography in DNA studies is the possibility of identifying particular cells that are synthesizing nucleic acid.
Proteins and nucleic acids are insoluble in cold acids and therefore precipitate to the bottom of the test tube.
These contain granules of a material called chromatin, which is rich in a nucleic acid, DNA (deoxyribonucleic acid).
Labeling DNA with a Radioactive Isotope Of the four bases in DNA, three are also found in the other nucleic acid, RNA; but the fourth, thymine, is found only in DNA.
The clarification of this apparent contradiction is found in the remarkable properties of the other nucleic acid, the translator molecule, RNA.
Nucleic acid is at present of unknown constitution; decomposition products are: phosphoric acid, uracil or 2.
The nucleic acids vary with the source of the proteids, there being considerable differences in chemical composition.
Both proteins and nucleic acids possess sufficient possible permutations of structure to permit storage of a lifetime's accumulation of information in an organ the size of the brain.
However, from the known regulatory ability of nucleic acids in specific protein synthesis, it is possible that the final repository is protein.
A variety of organic compounds have been synthesized by the action of various energy sources upon reducing atmospheres, and several investigators have extended the Urey-Miller-type reactions to synthesizenucleic acid components ([ref.
From the previously known ability of the nucleic acids to code genetic information, they are the prime suspects.
Brief electrical stimulation of cat cortical tissue causes an increase in nucleic acid cytidine and adenine, thus indicating a synthesis of altered polynucleotides.
Just what the intermediate stages are, on whether there are any, so far as the phosphorus is concerned, in the splitting up of nucleic acid by bacterial action is not determined.
The larger portion of the protein is of a comparatively simple type, in fact, consists of protamins most of which are in combination with nucleic acid as nucleoprotamins.
It does not seem that such are necessary since this is either split off from nucleic acid or results from the spontaneous oxidation of phosphine when this is formed under anaerobic conditions.
Compounds in which the phosphorus is in organic union with the protein molecule otherwise than a nucleic acid or lecithin.
Nucleic acid is rich in phosphorus and upon decomposition yields some of the purin bases (xanthin, adenin, guanin), a carbohydrate and phosphoric acid.
Rice from the University of London will be there presenting a seminar series on his work in nucleic acid synthesis in Oryzias.
The area of research that I have selected is concerned with the effects of physical and chemical agents on the synthesis of nucleic acids of the cell.
He feels quite strongly--but has no real evidence--that the synthesis of both types of nucleic acid are independent of each other and has pointed out some significant references that I did not know about.
We have found substantial evidence which demonstrates that there is no interconversion of the two types of nucleic acid.
The synthesis of both types of nucleic acid are independent of each other.
I had the good luck to talk to an outstanding man in the field of nucleic acid synthesis and he was quite enthusiastic about the caliber of our work.
I'm anxious to buckle down and really lick thisnucleic acid problem .
We will show, I hope, fairly conclusively that there is little or no interconversion between the two types of nucleic acid synthesis in the cell.
I now find that I have accumulated--as you suggested--three distinctly conflicting groups of data on nucleic acid synthesis of frog liver cells: 1.
I am afraid that your other suggestions are not germane to the problem of nucleic acid synthesis and metabolism, a problem that has been occupying all my time.
Should you be interested, we now have an article in press on the Journal of Cellular Physiology entitled: "Nucleic acid synthesis in the frog liver cell: A definitive study.
London, he introduced a solution of nucleic acid into, e.
The chemical bonds of this phosphorus in the molecules of nucleic substances were determined in later work.
The carbohydrate in this nucleic acid proved to be identical with D-ribose, which Emil Fischer had artificially made from arabinose and named ribose to indicate this relationship (1891).
Combined with the nucleic acids, they comprise the nucleus of the cell, which is the seat of the power of cell-division and, hence, of the growth of the organism.
The nucleic acids are complex compounds consisting of a carbohydrate, phosphoric acid, two purine bases, and two pyrimidine bases.
In both plants and animals, the purine bases which are a part of the nucleic acids undoubtedly play an important and essential part in growth, since they form the major proportion of the nucleus, from which all cell-division proceeds.
Nucleic acid, prepared from animal glands which contain large proportions of it, is a white powder, which is insoluble in water, but when moistened forms a slimy mass.
Solutions of nucleic acids are optically active, probably because of the carbohydrate constituents.
Mustards can modify the structure ofnucleic acids, cellular membranes, and proteins by combining with certain functional groups (particularly the sulfhydryl-containing enzymes) for which they have an affinity.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nucleic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
