No, it is perfect they way it is. In this case the verbe SER works as a link, joining the verb COCINAR with the rest of the sentence

I've never heard the term "polypeptide phrase" before, maybe they mean "polypeptide chain"? That's just a string of amino acids. It would help if you actually had the example in the question, then I could help better.

If this is a true genomic sequence, you can only start at a start codon, which is ATG.\n\nBut, this appears to be a template sequence, so we'll do transcription now:\n\nThe corresponding mRNA is:\nAUG AAU GGC UCU AAG AAG AAA UAG\n\nAUG is a valid start codon.  And by the way, that's methionine (Met or M).\n\nNow the rest:\nAAU=Asparagine (Asn or N)\nGGC=Glycine (Gly or G)\nUCU=Serine (Ser or S)\nAAG=Lysine (Lys or K)\nAAG=Lysine again (Lys or K)\nAAA=Lysine again (Lys or K)\nUAG=Stop codon\n\nSo the end sequence is Met-Asn-Gly-Ser-Lys-Lys-Lys, or in single-letters, MNGSKKK.

According to the CDC system, the genus Salmonella contains\ntwo species, each of which contains multiple serotypes\n(Table 1). The two species are S. enterica, the type species, and\nS. bongori, which was formerly subspecies V (19, 21). S. enterica is divided into six subspecies (4, 19), which are referred to by a Roman numeral and a name (I, S. enterica subsp. enterica; II, S. enterica subsp. salamae; IIIa, S. enterica subsp. arizonae; IIIb, S. enterica subsp. diarizonae; IV, S. enterica subsp. houtenae; and VI, S. enterica subsp. indica). S. enterica subspecies are differentiated biochemically (4, 19) and by genomic relatedness (6, 19, 21).\n\nCDC uses names for serotypes in subspecies I\n(for example, serotypes Enteritidis, Typhimurium, Typhi, and\nCholeraesuis) and uses antigenic formulas for unnamed serotypes described after 1966 in subspecies II, IV, and VI and in\nS. bongori (see discussion below). The name usually refers to\nthe geographic location where the serotype was first isolated.\nFor named serotypes, to emphasize that they are not separate\nspecies, the serotype name is not italicized and the first letter\nis capitalized (Table 2). At the first citation of a serotype the\ngenus name is given followed by the word “serotype” or the\nabbreviation “ser.” and then the serotype name (for example,\nSalmonella serotype or ser. Typhimurium). Subsequently, the name may be written with the genus followed directly by the\nserotype name (for example, Salmonella Typhimurium or\nS. Typhimurium) (18, 19). CDC uses the format for formula\ndesignations used by the WHO Collaborating Centre. Both\nversions of the serotype name are listed as key words in manuscripts to facilitate the search and retrieval of information on\nSalmonella serotypes from electronic databases.\n\nSerotype names designated by antigenic formulae include\nthe following: (i) subspecies designation (subspecies I through\nVI), (ii) O (somatic) antigens followed by a colon, (iii) H\n(flagellar) antigens (phase 1) followed by a colon, and (iv) H\nantigens (phase 2, if present) (for example, Salmonella serotype\nIV 45:g,z51:2. For formulae of serotypes in S. bongori, V\nis still used for uniformity (for example, S. V 61:z35:2).\n\nBefore 1966 all serotypes in all subspecies except subspecies\nIIIa and IIIb were given names. In 1966 the WHO Collaborating\nCentre began naming serotypes only in subspecies I and\ndropped all existing serotype names in subspecies II, IV, and\nVI and S. bongori from the Kauffmann-White scheme. For\nsurveillance purposes, i.e., for compatibility with old data, as\nstated above, CDC continues to use pre-1966 names for serotypes in subspecies II, IV, and VI and S. bongori (2, 3, 4). A\ncommon example of an old serotype name used at CDC and\nseen in the United States is S. ser. Marina (S. IV 48:g,z51:2).\nThe majority (59%) of the 2,463 Salmonella serotypes belong\nto S. enterica subsp. I (S. enterica subsp. enterica) (19).\nWithin S. enterica subsp. I, the most common O-antigen serogroups are A, B, C1, C2, D and E. Strains in these serogroups cause approximately 99% of Salmonella infections in humans and warm-blooded animals (19). Serotypes in S. enterica subspecies II (S. enterica subsp. salamae), IIIa (S. enterica subsp. arizonae), IIIb (S. enterica subsp. diarizonae), IV (S. enterica subsp. houtenae), IV (S. enterica subsp. indica), and S. bongori are usually isolated from cold-blooded animals and the environment but rarely from humans (10).

My gang translated R as "royal".\nAnyway the meaning of the phrase was an indeterminate small increment used in adjusting something (length, voltage, etc).

The phenotype is the physical expression of the genotype. In bacteria transformed with the pBLU plasmid and plated on the growth media containing IPTG and X-Gal will grow as either white colonies or blue colonies. pBLU is a plasmid that contains part of a gene called beta-galactosidase. The portion of the plasmid that contains this gene is called the multiple cloning site (MCS). (If you want to introduce foreign DNA into the plasmid, this is where you would introduce it.) The plasmid also has a gene for antibiotic resistance. The bacteria you use for transform with this plasmid must not already have this type of antibiotic resistance. If the bacteria are transformed with pBLU and plated on media with anibiotics only the bacteria that recieved the plasmid will grow. Those that were not transformed will die. If no DNA was inserted into the MCS of the plasmid then the for producing beta-galactosidase will be intact. This gene is called Lac Z. The transcription of this gene must be induced with a chemical called IPTG. So if the agar plate contained IPTG then the Lac Z gene will be induced and the protein beta-galactosidase will be produced. If this protein is produced it will cleave the chemical X-Gal (which was also on the plate) causing the X-gal to change from clear to blue.This causes the colonies to have a blue phenotype.\nIf the Lac Z gene was interrupted by foreign DNA in the MCS then no beta-galactosidase will be produced and the colonies will grow white.

Your teacher is crazy and using words that are not correct.  Though I believe that they mean "untwister".  Please tell your teacher to use correct terms.  If you want to impress them, tell them the "untwister" is actually called a topoisomerase.

One word contradicts your "facts". \n\nPlasmids.\n\nPlasmids are non-chromosomal loops of DNA found in bacteria.  They often contain antibacterial resistance genes, or give the ability to use different sugars.  These plasmids are commonly shared by bacteria.  This is a gain of genetic information.\n\nNow, it is true that we only have 4 types of nucleotides in DNA, and they make about 20 amino acids.  This is conserved in all life forms. But from this, a countless number of proteins can be made, and have a nearly infinite number of effects.  Your suggesting could be likened to saying that we can never invent a new word, since we only have 26 letters.  \n\nPlease provide a source for your claims, perhaps then we can understand how you arrived at such a conclusion.

This seems quite right to me, the only mistake I can find is "cahier de charge" instead of "cahier DES charges". \nYou could also say it that way :\n...son référentiel serait l'expérience intégrale de Paul Ricoeur...\n...son objet serait  la conscience adulte...\n(both "son" refering to "une philosophie des sciences")\nMaybe this sentence would be easier to understand if it was shorter, even to a french person like me (but that maybe because I know nothing about philosophy)...
