La hepatitis es una enfermedad contagiosa??

English:

Generally, hepatitis is not contagious by air. The only way to be infected is to be in contact with the objects that the contagious person used.

Spanish:

Generalmente, la hepatitis no se contagia por vía aérea. La única forma de infectarse es estar en contacto con los objetos que usó la persona contagiosa.

Explanation:

English:

It is known as a fecal-oral way of infection. The hepatitis is spread by blood, sperm, or other liquids from the body of the infected person. The intimate relation without protection is one of the ways.

Also, the drug addicts can be easily infected, if the needle is shared.

Spanish:

Se conoce como una forma de infección fecal-oral. La hepatitis se transmite por sangre, esperma u otros líquidos del cuerpo de la persona infectada. La relación íntima sin protección es una de las formas.

Además, los drogadictos pueden infectarse fácilmente si se comparte la aguja.

step 1: initiation

initiation is the beginning of transcription. it occurs 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.

step 2: elongation

elongation 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.

step 3: termination

termination 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.
