Tonsils are located in the lateral walls of the fauces of the oropharynx.

The answere is Palatine tonsils

Palatine tonsils, commonly called tonsils or faucial tonsils, are tonsils located on the left and right sides behind the throat, which can often be seen as flesh-colored, pink lumps. Tonsils are only present as "white bumps" if inflamed or infected with symptoms of exudate (pus drainage) and severe swelling.

Tonsillitis is tonsillitis and will often, but not necessarily, cause a sore throat and fever. In chronic cases, tonsillectomy can be indicated.

Palatine tonsils are located in the isthmus fauces, between the palatoglosic arch and the palatopharyngeal arch of the soft palate.  

Palatine tonsils are one of the mucosal-associated lymphoid tissues, which are located at the entrance to the respiratory tract and upper digestive tract to protect the body from the entry of exogenous material through the mucosal site. Because of this, it is the site of, and potential for focus, infection, and is one of the main immunocompetent tissues in the oropharynx. This forms part of the Waldeyer ring, which consists of adenoids, paired tubal tonsils, paired palatine tonsils, and lingual tonsils. From the pharyngeal side, they are covered with multilevel squamous epithelium, while fibrous capsules connect them to the pharyngeal wall. Through the capsule it passes through trabecules containing small blood vessels, nerves and lymphatic vessels. This trabecule divides the tonsils into lobules.

The nerves that supply the tonsil of the palatin originate from the maxillary division of the trigeminal nerve through the lower palatine nerve, and from the tonsillar branches of the glossopharyngeal nerve. The glossopharyngeal nerve continues through the palatine tonsils and innervates 1/3 of the posterior tongue to give a general sensation and taste. This nerve is most likely to be damaged during tonsillectomy, which causes a reduction in general sensation and taste sensation to the third of the back of the tongue.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
