If, at the time of the call to _creat( ), the specified file already exists, it is erased and all previous contents are lost unless the original file was write-protected. The _rtl_creat( ) function works like _creat( ) but uses a DOS/Windows attribute byte. The attrib argument may be one of these macros: FA_RDONLY FA_HIDDEN FA_SYSTEM Set file to read only Make hidden file Mark as a system file

LIFE COMPASS:

One of the roles that DNA plays is expression of genetic information. By expression we mean actually reading the instructions stored in DNA s nucleotide sequence and starting the process of building a protein from them. To explain how this happens, we first tell the short story, then tell it again but with some details. Even so, what follows is just a basic description of gene expression; we ll leave the finer points for a text in molecular biology. The short story is this: The DNA double helix unwinds to expose the nucleotide bases. A copy of the DNA nucleotide sequence is then made. This copy is in the form of a single-stranded ribonucleic acid (RNA). The single-stranded RNA molecule then moves to where protein synthesis will take place in the cell. We call this type of RNA messenger RNA (mRNA) because, like a messenger, it carries the blueprints from the DNA to the place where they are used to build a protein. Next, a complex group of proteins and RNA molecules read the nucleotide sequence in the mRNA and step by step link together the correct amino acids in the correct order (according to the instructions in the mRNA) to make a protein. That s the short story; now a little more detail: When the DNA double helix unwinds at the start of a gene (the beginning of a sequence that codes for a particular protein), there are individual ribonucleotides floating around in solution. These ribonucleotides form hydrogen bonds with the deoxyribonucleotides on one of the exposed strands of the DNA. Keep in mind that hydrogen bonding between nucleotide bases is pair specific. Then an enzyme called RNA polymerase catalyzes the biochemical reaction to covalently link the ribonucleotides together. The result is the single-stranded mRNA molecule whose base sequence is now complementary to the DNA sequence. Effectively the RNA molecule is a copy or transcript of the base sequence in the gene. So the process of synthesizing mRNA from DNA is called transcription. See Fig. 7-23. When protein synthesis takes place, a number of enzymes and ribonucleic acids get involved. One major player is a type of RNA called transfer RNA, (tRNA), whose job it is to transfer each amino acid to the correct location in the growing polypeptide chain. There are a number of different types of tRNA, one for each amino acid. Each tRNA molecule has two specific binding sites. One part of the tRNA molecule binds to a specific amino acid. The structure of this part of the tRNA molecule and the structure of the amino acid are such that the tRNA molecule binds specifically to that amino acid but not to others. The second binding site of the tRNA molecule has a specific nucleotide sequence, three nucleotides long, that can base-pair with the complementary sequence on the mRNA. In this way the tRNA molecules translate the mRNA sequence into a sequence of amino acids. Each three nucleotides in the mRNA are translated into a specific
