The Crohn’s disease can be an example of a disease associated with the digestive system.

The Crohn’s disease is a chronic inflammation of the gastrointestinal tract. Although it can be developed in any part of the gastrointestinal tract it is mostly aggressive ate the end of the small intestine to the passage to large intestine. It affects equally men and women and it starts usually between the ages of 15-35 years of age. It may appear because of genetic factors, environment, and simply an overactive inflammatory system.
It usually presents abdominal pain, rectal bleeding, frequent diarrhea, loss of appetite, weight-loss, and fatigue.
It is usually tested by blood tests to identify eventual deficiencies of vitamins or minerals, and other indicators of anemia or inflammation. Also fecal blood tests to identify if the problem could be a result of some kind of infection rather then Crohn's disease. Other tests may include X-rays, CT scans,or MRIs, leukocyte scintigraphy, endoscopy, and colonoscopy.

Answer from: Quest

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.
