CHAPTER XII

THE ENEMY WITHIN

It was getting late, but the Allenwood Sports Club prolonged its sitting at the Carlyon homestead. The institution had done useful work in promoting good fellowship by means of healthful amusements, but recently its management had fallen into the hands of the younger men, and the founders contented themselves with an occasional visit to see that all was going well. Some, however, were not quite satisfied, and Mowbray entertained suspicions about the Club. He was an autocrat, but he shrank from spying, or attempting to coerce a member into betraying his comrades. Some allowance must be made for young blood; and, after all, nothing that really needed his interference could go on, he felt, without his learning about it. Nevertheless, he had a disturbing feeling that an undesirable influence was at work.

Carlyon's room was unusually well furnished, and several fine London guns occupied a rack on the matchboarded wall. The cost of one would have purchased a dozen of the Massachusetts-made weapons which the prairie farmers used. The photograph of a horseman in English hunting dress with M.F.H. appended to the autograph was equally suggestive, and it was known that Carlyon's people had sent him to Canada with money enough to make a fair start. Unfortunately, he had not realized that success in farming demands care and strenuous work.

He sat with a flushed, excited face at a rosewood table, upon which the cigar ends, bottles, and glasses scarcely left room for the cards he was eagerly scanning. Gerald Mowbray leaned back in his chair, watching him with a smile. Emslie, the third man, wore a disturbed frown; opposite him, Markham sat with a heavy, vacant air.

CHAPTER XII

TOM SPEAKS HIS MIND

"Tom, Miss Harrow would like to see you."

It was an hour later, and the Rovers and the Laning girls had spent the time in watching the efforts of the others to put out the last of the fire. In the meanwhile, some of those present had gone through the addition to the main building and opened the various windows and doors, thus letting out the smoke. An examination proved that the damage done there was very slight, for which the seminary authorities were thankful.

"Wants to see me, eh?" returned Tom, musingly. "Well, I don't know whether I want to see her or not."

"You might as well go, Tom, and have it over with," suggested Sam.

"If I go, I want Nellie to go along," returned the brother. "I want her to know how I stand on this missing-ring question. By the way, how is she, all right?" continued the youth, addressing Stanley, who had brought the news that he was wanted.

"She seems to he all right, although she is very nervous. She says the reason she didn't hear the alarm and get out of the building in time, was because she had had a toothache and had taken a strong dose of medicine to quiet her nerves. Evidently the medicine put her into a sound sleep."

"How about the toothache?" asked Sam, slyly.

"Oh, that's gone now; the fire scared it away."

"Where is she?" questioned Tom.

"She is in the office with some of the other teachers." What are the answers to this following set of questions: 1. Who wanted to see Tom?
2. Who did Tom want with him?
3. How was the smoke getting out?
4. Was Miss Harrow ok?
5. who reported that
6. which girls watched what was happening?
7. Why did Miss Harrow not hear?

Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the letters G, U, A, and C to denote the nitrogenous bases guanine, uracil, adenine, and cytosine) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis, a universal function where RNA molecules direct the assembly of proteins on ribosomes. This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to form proteins.

Like DNA, most biologically active RNAs, including mRNA, tRNA, rRNA, snRNAs, and other non-coding RNAs, contain self-complementary sequences that allow parts of the RNA to fold and pair with itself to form double helices. Analysis of these RNAs has revealed that they are highly structured. Unlike DNA, their structures do not consist of long double helices, but rather collections of short helices packed together into structures akin to proteins. In this fashion, RNAs can achieve chemical catalysis (like enzymes). For instance, determination of the structure of the ribosomean enzyme that catalyzes peptide bond formationrevealed that its active site is composed entirely of RNA.
